SKU: SEN0492
This Laser Ranging Sensor (SEN0492 RS485) detects objects in 4~400cm with ±2cm accuracy, supporting 3 modes for scenarios like security gates, access control, alarms, smart trash cans, and obstacle avoidance. It’s waterproof/shockproof, filters optical interference, uses invisible laser, and operates at 5V-36V. With an industrial 485 chip (Modbus-RTU), it triggers Low output when distance is below your threshold. Note: Data is unstable for black objects.
