Industrial Laser Ranging Sensor (4-400cm, RS485, Modbus-RTU, IP67)

The Industrial Laser Ranging Sensor provides non-contact distance measurement from 4 to 400 cm with an accuracy of ±2 cm. Built with a rugged IP67-rated metal housing and RS485 communication, it suits automation engineers, robotics makers, and industrial prototyping applications.

Accurate 4 to 400cm measurement range

The sensor delivers reliable ranging performance across a 4 cm to 400 cm detection span with ±2 cm accuracy. This makes it ideal for position detection, obstacle avoidance, and liquid level monitoring.

RS485 Modbus-RTU communication

Equipped with an RS485 interface running the standard Modbus-RTU protocol, the sensor integrates seamlessly with PLCs and microcontrollers over long cable runs.

Rugged IP67 metal housing

The unit features a sealed metal enclosure with an IP67 rating to resist dust and water ingress. It is built to withstand harsh, demanding operational environments.

Wide 6 to 36V power input

A broad operating supply range of 6V to 36V DC allows direct connection to common industrial power rails and automotive electrical systems.
