PRODUCT DESCRIPTON

The ERDI LASER® SPD1200N2 is an ultra-compact 905nm laser rangefinder module designed for precise distance measurement from 0.2 m to 1200 m, with nighttime capability up to 1500 m. Featuring a lightweight sealed structure and low power consumption, the module is optimized for portable, embedded, and space-constrained systems requiring reliable short-to-mid range measurement performance.

Key Advantages

  • Ultra-Compact Structure: Miniature dimensions for highly integrated embedded systems.
  • Lightweight Design: Approx. 5 g for portable and UAV applications.
  • Stable Measurement Capability: High ranging accuracy with reliable outdoor performance.
  • Sealed Optical Structure: IP67 protection inside the lens cavity.
  • Low Power Consumption: Average operating power around 0.45 W.
  • Easy OEM Integration: UART-TTL interface with protocol support.
