Dimensions	≤ 116 mm × 52 mm × 96 mm
Weight	≤ 680 g
Electrical characteristics	Input voltage: DC 18 V to 32 V The electrical and electronic components inside the laser rangefinder/designator are compatible with the system power characteristics. Average power: ≤ 80 W; peak power: ≤ 120 W After PCB design and debugging are completed, all circuit boards are coated with conformal coating to provide moisture, salt-spray and fungus protection.
External power input requirements	When sharing the same power supply with motor or other inductive loads, the laser rangefinder/designator should use a soft-start (3–5 s). At the instant of sudden power-on, the induced voltage generated by motors and other inductive loads at the module input may be several times the nominal input voltage, which can cause over-voltage damage. During power-up, it is recommended to use the dedicated power-on control function of the laser rangefinder/designator to stagger its power-on time from other loads. After other loads have powered up and stabilized, then enable power to the rangefinder/designator. The power input of the laser rangefinder/designator should be isolated from other inductive loads. If conditions allow, a DC filter (30 V / 10 A) can be added at the module’s power input. The power supply for the laser rangefinder/designator shall satisfy the peak power demand. When testing the module alone, with a DC supply voltage of 24 V, the supply current should be greater than 6 A. If the output voltage is lower, the rated output current of the supply should be increased accordingly.

Duration: 1 hour per axis in three orthogonal directions (X, Y, Z). Test conditions: The product shall be mounted on the vibration platform in its normal operating configuration and powered on during testing. After vibration testing, the equipment shall operate normally.

Test conditions: The product shall be mounted on the shock test platform in its normal operating configuration and powered on during testing.

Meet the LR2000E4

The LR2000E4 is a compact ranging module in the E4 mechanical format. It provides digital distance measurements for equipment that needs a ranging subsystem rather than a standalone handheld meter.

Its standard measurement range is 4–2000 m. For distances above 400 m, the accuracy table uses a distance-dependent term of 0.4% of D. Use the model-specific accuracy formula when setting your system requirements.

The UART-TTL interface supports host-controlled measurements. The manual includes test-software guidance, a six-pin interface definition, and a hexadecimal communication protocol. Use the E4 drawing for packaging and mounting; an E2 drawing is not an interchangeable mechanical reference.

LR2000E4 Specifications

Read performance values with their target and test conditions. The linked user manual provides the complete mechanical, electrical, and communication details.

• For civilian equipment only. The model manual prohibits military applications.

Operation and Data Output

Single-shot mode requests one reported distance. For a weak return, the manual describes repeated internal measurements before reporting stable distance data. Continuous mode produces repeated results at the documented adaptive update rate.

The standard measurement-rate specification is 2–10 Hz (adaptive). Use the current protocol table for command timing and output format.

Meet the LRF3000A1

The LRF3000A1 extends this selection to a 3000 m range class while keeping a TTL-level UART host interface. The maximum-range condition is explicit: a building target with 70% reflectivity, clear weather, and visibility of at least 4 km.

The minimum-range entry is 1 m on a 90%-reflectivity whiteboard. These minimum and maximum figures use different targets; they should not be combined into an unconditional all-target range guarantee.

Normal mode provides a 3–10 Hz adaptive update rate, while long-range mode is specified at 1–10 Hz. The electrical specification allows 3.3–5 V DC with supply ripple below 0.1 V.

LRF3000A1 Specifications

Read performance values with their target and test conditions. The linked user manual provides the complete mechanical, electrical, and communication details.

• Use the model-specific mechanical drawing for the mounting geometry and tolerances. Overall installation clearance is evaluated separately from individual housing dimensions.
• For civilian equipment only. The model manual prohibits military applications.

Operation and Data Output

Select normal or long-range measurement mode through the model’s communication protocol. The mode determines the documented adaptive output-rate range.

In low-power mode the controller is off and does not respond to ordinary commands. Use the model-specific enable input and wake-up sequence before requesting or processing a ranging result.

SPD1200N3 combines a 905 nm ranging laser and single-photon receiver with a laser-indication function. ERDI confirms that its ranging laser and receiver are shared with SPD1200ZG; the model-specific ranging limits, mechanical design and indication functions must still be evaluated separately.

SPD1200ZG provides inertial orientation information. SPD1200N3 provides laser indication instead; this is not a claim of a six-axis IMU, compass heading or 3D point-to-point measurement for N3.

The N3 specification states a 3–1000 m range on a building target under visibility of at least 10 km and humidity no greater than 60%. The nominal rectangular body is 14 × 18 × 22.3 mm and weighs no more than 6 g.

Read the values together with their source conditions. Literature and related-model data do not replace these ratings.

Functional Description

Single measurement initiates one target-distance measurement and returns the result over the serial interface; the source describes repeated acquisition for low-reflectivity targets until a stable reading is obtained.

Continuous measurement repeatedly reports target distance at a distance-dependent 2.5–15 Hz update rate.

The serial baud rate can be configured to match host requirements. Use firmware-matched packet definitions and test command, response, checksum and failure handling on the ordered configuration.

Six-Axis Inertial Measurement Explained

A conventional six-axis IMU comprises three orthogonal gyroscope angular-rate channels and three orthogonal accelerometer specific-force channels. Six-axis describes six sensing channels, not six independent rotational axes. [6]

Angle reporting is configurable and does not imply that the standard customer interface exposes all six raw sensor channels. Available outputs are defined by the configuration-matched interface protocol.

For a fixed single-axis rotation, the conceptual relationship is θ(t) = θâ‚€ + ∫ω(t)dt. Angular-rate bias and noise create accumulated angle drift. Three-axis attitude estimation requires an appropriate coordinate convention. [5]

Integration error accumulates during motion. This is relative heading, not an absolute north-referenced compass specification.

Coordinate Convention

Use the current manual's X/Y/Z convention when interpreting angle-enabled output.

Coordinate AxesThe Y axis points toward the lenses. Use the coordinate convention in the current user manual.

SPD1200N2 OEM Ranging and Integration

SPD1200N2 is a compact 905 nm laser ranging module with a 0.2–1200 m source-table ranging distance. The source documents UART-TTL communication and a model-specific square housing.

Functional Description

The source lists baud-rate modification as a serial-interface function.

Single ranging measures the target once. For a low-reflectivity target, the source says the module repeats measurements until stable distance data is obtained and reports it through the serial interface.

Repeated-ranging mode performs continuous distance measurement. The functional section states a typical configurable 2 Hz refresh rate and a maximum of 15 Hz; the formal frequency row separately retains both 2–15 Hz and 4–15 Hz alternatives.

Meet the LR1200E4

The LR1200E4 is a compact ranging module in the E4 mechanical format. It provides digital distance measurements for equipment that needs a ranging subsystem rather than a standalone handheld meter.

Its standard measurement range is 4–1200 m. Accuracy is specified in two distance intervals, with a distance-dependent term above 400 m. Use the model-specific accuracy formula when setting your system requirements.

The UART-TTL interface supports host-controlled measurements. The manual includes test-software guidance, a six-pin interface definition, and a hexadecimal communication protocol. Use the E4 drawing for packaging and mounting; an E2 drawing is not an interchangeable mechanical reference.

• For civilian equipment only. The model manual prohibits military applications.

Operation and Data Output

Single-shot mode requests one reported distance. For a weak return, the manual describes repeated internal measurements before reporting stable distance data. Continuous mode produces repeated results at the documented adaptive update rate.

The standard measurement-rate specification is 2–10 Hz (adaptive). Higher-rate custom versions mentioned in the manual are separate configurations, not the default performance of a standard unit.

Meet the LRF1200A1

The LRF1200A1 is a cylindrical ranging module for compact instruments that need a serial distance output. Its specification lists a building-target measurement range of 5–1200 m and an update rate of 1–3 Hz.

The 0.1 m display increment is distinct from ranging accuracy. Accuracy is ±1 m from 5 to 100 m and follows a distance-dependent formula above 100 m. This distinction helps define a realistic display and acceptance test.

Electrical integration differs from the E series: the specified supply is 3.3 ± 0.1 V DC, not a general 3.3–5 V input range. Use the LRF1200A1 pin definition, low-power behavior, and communication protocol.

Operation and Data Output

The host uses the serial communication protocol to operate the ranging module. The low-power mode turns the controller off, so it does not respond to normal commands while asleep.

The manual describes an active-low enable input for normal operation and a high level for low-power mode. Use the LRF1200A1 interface and timing definitions rather than an E-series wiring assumption.

HW256 at a glance

The HW256 is a compact 1× thermal fusion sight that combines a red-dot aiming channel with an uncooled thermal imaging channel in one housing. The red dot gives rapid target acquisition and a precise aiming point; the thermal channel renders target outlines and scene detail in low light, darkness, smoke and dust. The sight therefore remains usable by day and by night without changing hardware.

A 1× optical system is used with both eyes open, so the HW256 can be brought onto a target in the same way as a conventional red-dot sight. Thermal imagery is presented on an OLED display and can be viewed together with the red-dot reticle for fusion observation. The detector resolves 256 × 192 pixels on a 12 µm pitch behind a 19 mm lens, giving a 9° × 6.7° field of view.

The housing is machined from aircraft-grade aluminium with a black hard-anodised finish. A standard Picatinny interface with a quick-release lever allows tool-free fitting and removal, and the 38 mm optical-axis height matches common rail and mount combinations. The supplied document describes intended use for close- to medium-range work on submachine guns, assault rifles and similar platforms, including urban operations and indoor CQB, subject to local law.

Key features

• Thermal and red dot in one sight for day and night use.
• Three reticle styles: dot, circle, and dot with circle.
• Three thermal image modes: black hot, white hot and outline.
• 256 × 192 uncooled vanadium-oxide detector, 12 µm pixel pitch, 19 mm lens, 9° × 6.7° field of view.
• OLED display, 1024 × 768 pixels.
• 1× / 3× / 5× digital zoom; digital zoom reduces the field of view.
• 15 daylight + 5 night-vision red-dot levels and 10 thermal brightness levels.
• Red-dot-only runtime ≥ 10,000 h; fusion-mode runtime ≥ 6 h.
• Full CNC aluminium housing with black hard-anodised finish for rigidity and stable zero retention.
• 30 × 23 mm viewing window and a quick-release Picatinny mount with a clamp-adjustment knob.
• IP67 sealed housing, stated for −20 °C to +65 °C operation.

How thermal fusion works

Every object above absolute zero emits infrared radiation, and the amount and spectrum depend on its temperature and emissivity. An uncooled thermal detector converts the incoming long-wave infrared radiance into an electrical signal and then into a visible image. Warmer objects can be displayed brighter (white hot) or darker (black hot), or rendered as an outline that emphasises temperature transitions.

The HW256 adds a red-dot aiming channel to that thermal image. The red dot provides a precise, high-contrast aiming point for rapid acquisition, while the thermal channel reveals target outlines that may be difficult to see with a conventional optic in low light, darkness, smoke or dust. Presenting both channels in one 1× sight avoids switching hardware between day and night configurations.

Thermal imagery is not a photograph and is not a calibrated temperature map. Image contrast depends on the temperature difference between the target and its background, atmospheric transmission, distance, focus and the selected palette. The HW256 is an imaging and aiming sight, not a radiometric thermometer.

Performance conditions and limits

• Thermal contrast depends on the target-to-background temperature difference and emissivity. A scene with little thermal contrast may show little detail even when the detector is working correctly.
• Atmospheric transmission is reduced by fog, heavy rain, dust, smoke and long distance. Thermal imaging can help in smoke or dust, but it does not guarantee seeing through every obscurant.
• Ordinary glass blocks much of the long-wave infrared band used by thermal imagers. A thermal sight generally cannot image through a closed window or glass barrier; confirm the optical path.
• Runtime depends on mode, brightness, zoom, calibration frequency, battery type and temperature. The quoted red-dot-only and fusion-mode figures are separate operating conditions.
• Digital zoom enlarges the central part of the image; it does not add optical resolution or target detail.
• IP67 is a manufacturer-stated rating. IEC 60529 defines the IP code; citing the standard does not certify this product. IP67 is not a diving or high-pressure-washing rating.
• Zero retention after removal, impact or mount changes must be confirmed on the host; the supplied manual describes the inspection and adjustment process.

Intended use and application scenarios

The supplied document describes the HW256 for close- to medium-range work on submachine guns, assault rifles and similar platforms, including urban operations and indoor CQB. It is an aiming aid: it does not replace safe firearm handling, marksmanship training or compliance with local law.

• Day/night patrol and security use where both a rapid red-dot aim point and thermal target detection are useful.
• Urban and indoor close-quarters scenarios where target outlines may be obscured by low light, shadow, smoke or dust.
• Hunting where lawful, particularly in low-light conditions where thermal contrast reveals animals against vegetation or ground.
• Sport shooting and professional training on 1913-rail rifles and carbines.
• Observation and detection of heat-emitting targets before positive identification with other sensors or lighting.

Application examples describe configuration possibilities, not a guarantee of detection, identification, hit probability or legality in a particular jurisdiction. Confirm local law and range rules before use.

Mounting, power and configuration

The HW256 fits a MIL-STD-1913 Picatinny rail with its quick-release mount. Confirm that the rail and mount are mechanically sound, that the mount is fully seated and locked, and that the sight cannot move by hand before use. The 38 mm optical-axis height should be checked against the host’s stock, cheek weld and any magnifier or clip-on.

Power is supplied by one CR123A cell (3 V or 3.7 V). The Type-C 5 V input can power the sight but does not charge the cell according to the manual. The red dot and thermal channel have separate power and brightness logic; the supplied manual gives the complete button, reticle, zoom, calibration and inspection procedure. This page intentionally does not reproduce operating instructions.

Thermal performance is configuration-dependent. Confirm the image focus, palette, brightness and reticle for the intended environment, and verify zero after mounting or changing the host configuration.

Care, storage and safety

• Wipe outer surfaces with a cloth moistened with water, mild soap solution or alcohol. Blow loose particles off the optics, then clean the glass with a lens tissue and an optical solvent.
• Clean the battery compartment with a suitable solvent and let it dry fully. Check the mount, O-rings and covers periodically.
• If the sight is not used for a long period, remove the cell, store it in a dry, dust-free place below 80 % relative humidity, away from acids, alkalis and corrosive vapours, and check the sight every three months.
• Do not open the housing, modify the sight or attempt repairs. Refer visible damage or unexplained faults to qualified service personnel.
• Before installing, adjusting or servicing the sight, make sure the firearm is unloaded, the chamber is empty and the muzzle is pointed in a safe direction. Wear eye and hearing protection when shooting.
• Do not point the sight at the Sun, lasers, welding equipment or other high-intensity heat sources. Do not use it as solar-viewing equipment.
• Do not dispose of lithium cells with household waste; follow local recycling and disposal rules.
