Setup and function
Overview
The deTem2 Core IP69K multiple light beam safety device is an electro-sensitive protec‐
tive device (ESPE) consisting of a sender and receiver.
Parallel infrared light beams between the sender and receiver protect the hazardous
area. When one or more light beams are completely interrupted, the multiple light beam
safety device 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 dan‐
gerous state.
Sender and receiver automatically synchronize themselves optically. An electrical con‐
nection between both components is not required.

Beam separation and number of beams
The beam separation is the distance between two adjacent light beams, measured
from the center of one beam to the center of the next.
The beam separation and number of beams depend on the device variant.
