Operating principle
Photoelectric slot sensors are photoelectric sensors that operate according to the thru-beam
sensor principle. The transmitter sends signals directly to the receiver. If an object breaks the
light beam, the switching element function is triggered. The special U-shaped design means
the transmitter and receiver can be accommodated in one housing, which ensures high resis-
tance to vibrations. In contrast to standard thru-beam sensors, photoelectric slot sensors have
the added advantage of not requiring complex electrical installation, as only one device needs
to be connected. Also, adjustment of the optical axes is not necessary.
