This chapter provides information on the operation of the safety light curtain and shows
examples of its range of use.
The deTec2 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 re‐
ceiver that protects the hazardous area (hazardous point, access and hazardous area
protection). When one or more beams are completely interrupted, the safety light cur‐
tain reports the interruption in the light path to the secure output signal switching devi‐
ces (OSSDs) by a signal change. The signal to stop the dangerous state of the machine
must be evaluated by a safe control or safety relay (contactors).
Sender and receiver automatically synchronize themselves optically. An electrical con‐
nection between both components is not required.
Figure 1: Sender and receiver
The protective field height indicates the range within which the test rod belonging to
the safety light curtain is detected. The size of the safety light curtain determines the
protective field height. The design and construction of the safety light curtain deTec2
Core extends the protective function of a device to the end of the housing without any
blind spots.
