Meet the LR1500E2
The LR1500E2 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 4–1500 m. The accuracy table uses a 500 m breakpoint, with a separate distance-dependent formula for longer measurements. 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.

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.
