Diffuse-mode sensing is the most common type of proximity sensing. In diffuse mode sensing, light emitted from the sensor strikes the surface of the object to be detected and is diffused, sending some light back to the receiver element of the sensor.

How do diffuse photoelectric sensors work?

Diffused Photoelectric Sensors have the emitter and receiver together in the same component. For the Diffused sensor to work, the sensor’s emitter needs to be pointed at an object so the light travels from the sensor’s emitter to the object and then bounces back to the sensor’s receiver.

What is diffuse with background suppression?

Diffused with background suppression: Diffused sensors with background suppression sensors have a defined sensing range for any object regardless of color, reflectivity or finish. They are able to detect dark objects placed directly on shiny backgrounds and can be easily installed and adjusted.
