Thru beam photoelectric sensors

Photoelectric sensors with a single transmitter and single receiver are placed in opposite to each other. The transmitter sends an infrared beam to the receiver. When an object interrupts the light beam, the output is activated. A transmitter / receiver photoelectric sensor is a very reliable way of detecting and the high excess gain of our sensors are suited for extremely polluted environments. Our thru beam sensors can reach up to 70 meters!
