TSD20 Short Distance Laser Sensor Module High Speed Proximity Detection For Robotics and Industrial Applications

Description:

The TSD20 Short Distance Laser Sensor Module with a high-sensitivity SPAD sensor to deliver precise single-point ranging—0.05–20 m on 90% reflective targets and 0.05–10 m on 10% reflectivity—ideal for drones, robots, and automation needs. At 200 Hz, it ensures lightning-fast refresh rates, backed by ±5 cm accuracy under 5 m and 1% beyond, with exceptional ±10 mm repeatability, making it ultra-reliable in dynamic environments.

 Its robust optical design resists up to 100 KLux of ambient light, and the 905 nm Class 1 eye-safe laser ensures user safety while maintaining sharp focus with a 3.4° field of view. Powered by just 3–3.6 V and consuming under 0.4 W, it’s optimized for battery-operated systems. Engineered to endure –20 °C to +60 °C, with UART/I²C interfaces, it blends high performance, durability, and integration ease.
