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 the sensor's maximum permissible tightening torque of < 1,3 Nm.
The sensors must be connected in a voltage-free state. The following information must
be observed, depending on the connection type:
– Male connector connection: Note pin assignment
– Cable: wire color
Only supply/switch on the voltage once all electrical connections have been estab‐
lished.
Explanations of the connection diagram (following tables):
Alarm = alarm output
Health = alarm output
MF (pin 2 configuration) = external input, teach-in, switching signal
Q /C = switching output, IO-Link communication
