Fork light barriers
Frame light barriers from Dietz work like through-beam light barriers. Transmitter, receiver and electronics are combined in a single sturdy metal housing.
The easy installation without time-consuming alignment, short response times and a high resolution are crucial advantages compared to conventional through-beam light barriers, make possible in practice the exact positioning and a reliable detection of even the fastest movement sequences.
The sensors have a sensitivity adjustment and mostly can be toggled between normally open and closed. Clocked red or infrared light guarantees a high ambient light immunity.
