Square photoelectric sensor EW-LT61/81
Basic Info
Model No.: EW-LT61/81
Product Description
Photoelectric Sensor EW-LT61/81 (Square Switch Sensor Photoelectric & Through-Beam Type Switch Sensor)
Features of the square photoelectric sensor: Non-contact detection is possible without mechanical contact with the detection object, so no damage is caused to the detection object or the sensor. As a result, the sensor can be used for a long time.
