Product Model: NTLRA200M
Eye Safety Level: Class 1
Product Overview:
The NTLRA200M is a Class 1 eye-safe 905nm laser rangefinder module designed for industrial automation, UAV navigation, and robotic positioning. It delivers a 0.05–200m measurement range (≥50% target reflectivity) with high accuracy: ≤±0.05m (≤10m) and ≤0.1m (>10m), ideal for long/short-distance industrial tasks.
With -40℃~+65℃ extreme temperature resistance, it performs reliably in severe cold, high heat, and harsh outdoor conditions. Features include 9–36V wide DC voltage, <2W low power consumption, 3.3V TTL/RS422 dual interfaces, and 7 adjustable baud rates (19200bps–921600bps) to avoid data bottlenecks. Its ultra-compact size (25×33×46mm, ≤50g) enables easy integration into space-constrained setups.
