1. Photocell one-way light barrier 20m
    The 20-metre one-way photocell uses the SOMMER 2-wire system. Only two wires are required on the transmitter and the receiver side, while the polarity is optional. The fact that the board is rotatable through 180° means additional installation options, and no mounting brackets are required. And with IP code IP55, it is suitable for outdoor use. Learn More
