How does a Laser Sensor Work with Relay?

Laser sensors use focused coherent light to measure the distance to a target object, which are often used to check for the presence of parts. Laser sensors are used in factory automation, typically for products or mechanical parts. The instrument can detect any kind of solid, and the output is proportional to the distance measured, independent of material, color and luminosity. Laser displacement switches are often used to provide high resolution output to provide position or displacement such as PLCs. For enhanced stability, the output signal is usually precise and includes temperature compensation.

This is ATO diffuse reflection laser sensor. Its detection distance is 300mm.

Connect the circuit according to the circuit diagram. We use a relay as its load.

When an object blocks the beam, the sensor is excited.
The sensor is activated and the relay is controlled.
