3.1 Structure and function
Overview
T
he deTec4 Core Vibes safety light curtain is an electro-sensitive protective device
(ESPE) consisting of a sender and receiver.
A series of parallel infrared light beams forms 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 safely analyze the
signals (for example using a safe control or safety relays) and stop the dangerous state.
Sender and receiver automatically synchronize themselves optically. An electrical con‐
nection between both components is not required.

Protective field height
T
he protective field height indicates the range within which the test rod belonging to the
safety light curtain is reliably detected.
Protective field width
T
he protective field width is the dimension of the light path between sender and
receiver. The maximum protective field width is limited by the scanning range.
Resolution
T
he resolution describes the size of the smallest object detected by the safety light
curtain in the protective field. The resolution corresponds to the diameter of the test rod
belonging to the safety light curtain.
The safety light curtain has a resolution of 30mm. This resolution provides hand
pr
otection.
Scanning range
T
he scanning range is the maximum protective field width.
The sensing sensing range is dependent on the receiver used.
