EATON 55 Series Photoelectric Sensors

What are the different sensing modes in photoelectric sensors?

The sensors also have different sensing modes like diffuse, retroreflective and through-beam.

• In diffuse mode, the sensors emit a light beam. The emitted light is then scattered by an object, allowing the sensor to detect the object even if it is not directly in the path of the light beam.
• In retroreflective mode, the sensors emit a light beam that is reflected back to the sensor by a retroreflective target. This mode is generally used for applications where the object is moving at high speeds.
• In through-beam mode, the sensors emit a light beam to pass through an object and get detected by the sensor on the other side. This mode is generally used for applications where the object is large or opaque.

Can photoelectric sensors detect transparent objects?

Some photoelectric sensors like retroreflective sensors & diffuse reflective sensors can detect transparent objects by reflecting light off the surface of the object. However, through-beam sensors may not be able to detect transparent objects.

How can I adjust the sensitivity of a photoelectric sensor?

Users can adjust the sensitivity of a photoelectric sensor by adjusting the distance between the sensor & the object being detected or by adjusting the amount of light emitted by the sensor.

Can photoelectric sensors be used in outdoor environments?

Yes, photoelectric sensors can be used in outdoor environments and are rated for use in specific temperature and weather conditions.
