Meet the LR1000E2
The LR1000E2 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 4–1000 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 E2 drawing for packaging and mounting.
01
1000 m range class
4–1000 m standard range with a model-specific long-distance accuracy formula.
02
Host-controlled ranging
3–10 Hz (adaptive); single-shot and continuous measurement modes.
03
Compact integration
25.7 × 13.3 × 24.6 mm nominal dimensions in the current mechanical drawing; detailed tolerances remain controlling.
04
UART-TTL interface
115200 bps communication and a 3.3–5 V supply range; use the model-specific pinout and command table.

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 3–10 Hz (adaptive). Use the current protocol table for command timing and output format.
