This chapter provides information on the operation of the safety light curtain and shows
examples of its range of use.
The deTec4 Core safety light curtain is an electro-sensitive protective device (ESPE)
consisting of a sender and receiver.
A series of parallel infrared light beams form a protective field between sender and
receiver that protects the hazardous area (hazardous point, access, and hazardous
area protection). When one or more beams are completely interrupted, the safety light
curtain reports the interruption in the light path to the secure output signal switching
devices (OSSDs) by a signal change. The machine or its control must evaluate the sig‐
nals reliably (e.g., by means of a safety controller or a safety relay) and bring an end to
the dangerous state.
Sender and receiver automatically synchronize themselves optically. An electrical con‐
nection between both components is not required.
