PRODUCT DESCRIPTON

The ERDI LASER® LR600D23 is a new-generation compact 905nm laser rangefinder module designed for precise distance measurement in lightweight electro-optical and embedded systems. Based on advanced Time-of-Flight (ToF) technology, it delivers stable measurement performance within a 5 m to 600 m range, with an adjustable refresh rate of 2–10 Hz to accommodate various application requirements.

Featuring a compact cylindrical structure, low power consumption, and high measurement reliability, the LR600D23 is optimized for seamless integration into UAV payloads, handheld thermal imaging devices, and portable laser systems. The module supports a UART-TTL communication interface and includes test software and communication protocol documentation, enabling fast integration and efficient secondary development.

Designed for stable operation in diverse environments, it provides a reliable distance sensing solution for both professional and industrial applications.


Key Advantages

  • Stable Medium-Range Measurement: Provides reliable distance measurement from 5 m to 600 m with typical ±1 m accuracy.
  • Compact & Lightweight Structure: Cylindrical design (Ø23 mm × 47 mm) with only ~20 g weight, suitable for portable and embedded electro-optical systems.
  • Adjustable Measurement Frequency: Supports configurable 2–10 Hz ranging frequency for flexible system integration.
  • Low Power Consumption: Optimized efficiency with <0.65 W operating power, suitable for battery-powered platforms.
  • Easy Integration & Development: UART-TTL interface with complete protocol documentation for rapid integration and secondary development.
  • Reliable Performance: High valid measurement rate (≥98%) with low false alarm rate (≤1%) ensures stable operation in practical environments.
