Mount the sensor and the reflector using suitable mounting brackets (see the SICK
range of accessories). Align the sensor and reflector with each other.
NOTE
Note the sensor's maximum permissible tightening torque of 0.56 Nm.
Operation in standard I/O mode:
The sensors must be connected in a voltage-free state (U
tion must be observed depending on the connection type:
– Plug connection: pin assignment
– Cable: wire color
Only apply voltage/switch on the voltage supply (U
tions have been established.
The green LED indicator on the top of the sensor lights up.
Operation in IO-Link mode: Connect the device to a suitable IO-Link master and inte‐
grate in the master or control via IODD/function block. The green LED indicator flashes
on the sensor. IODD and function block are available to download from
under the part number.
