Omron E3Z-D81 2M Diffuse Photoelectric Sensor

The Omron E3Z-D81 2M diffuse photoelectric sensor is a diffuse‑mode sensor from Omron with a 2-meter sensing range, designed for non-contact detection of targets using light reflected from the surface. In diffuse mode, the sensor senses light reflected by the object to trigger its output, enabling simple presence detection without passing a separate reflector. The E3Z-D81 designation identifies it as part of Omron’s E3Z family of diffuse photoelectric sensors, providing a straightforward electrical interface and reliable detection within the specified distance. With a 2-meter sensing range, this model supports short-range, non-contact detection tasks in automation setups where keeping moving parts free from wear is advantageous.
