Meet the LR2000E2

The LR2000E2 is a compact ranging module in the E2 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 E2 drawing for packaging and mounting.

2000 m range class

4–2000 m standard range with a model-specific long-distance accuracy formula.

Host-controlled ranging

2–10 Hz (adaptive); single-shot and continuous measurement modes.

Compact integration

25.7 × 13.3 × 24.6 mm nominal dimensions in the current mechanical drawing; detailed tolerances remain controlling.

UART-TTL interface

115200 bps communication and a 3.3–5 V supply range; use the model-specific pinout and command table.

TECHNICAL DATA

LR2000E2 Specifications

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

Parameter	Value	Conditions / notes
Laser wavelength	905 ± 5 nm	�
Measurement range	4–2000 m	Standard range; actual reach depends on target and environment.
Ranging accuracy	±1 m (D ≤ 400 m); 0.4% of D (400 m < D ≤ 2000 m)	Target reflectivity and size are not specified in the accuracy table.
Measurement update rate	2–10 Hz (adaptive)	Completed distance outputs; not the optical pulse-repetition rate.
Communication interface	UART-TTL	Custom configurations are specified separately.
Baud rate	115200 bps	�
Supply voltage	3.3–5 V	�
Operating temperature	−20 �C to +60 �C	�
Storage temperature	−40 �C to +60 �C	�
Mechanical drawing dimensions	25.7 × 13.3 × 24.6 mm	Drawing nominal values. Observe the individual tolerances in the model drawing; do not machine from the rounded summary alone.
Laser safety class	Class 1	As stated in the model manual; finished-equipment assessment is separate.
Laser beam divergence	< 6 mrad	�
Optical material	PMMA	�
Receiver aperture	9.2 mm × 14.5 mm	�
Startup time	≤ 200 ms	�
Inrush current	< 400 mA	�
Operating power consumption	≈ 1.2 W	Approximate value in the specification table.

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.

Electrical Interface

Pin	Signal	Function
1	GND	Power ground
2	VCC	Power input
3	I/O (Reserved)	Reserved for expansion
4	TXD	Transmit data: module → host
5	RXD	Receive data: host → module
6	SW-SHOT	Function-enable input. The required control polarity must match the supplied configuration.
