5 Electrical installation
Operation in standard I/O mode:
The sensors must be connected in a voltage-free state. The following information must
be observed, depending on the connection type:
– Male connector connection: Pin assignment
– Cable: Wire color
Only apply voltage and switch on the voltage supply once all electrical connections have
been established.
Operation in IO-Link mode: Connect the device to a suitable IO-Link master. Integrate
into the master or into the controller using IODD/function block. The green LED
on the sensor pulsates. IODD and function block are available to download from
www.sick.com under the part number.
Explanation of the connection terminology used in the following tables:
BN = brown
WH = white
BU = blue
BK = black
Q1 = Digital output 1
Q2 = Digital output 2
Q3 = Digital output 3
C = IO-Link communication
L+ = Supply voltage (U
V
)
M = Ground
DC: 10 ... 30 V DC, see "Technical specifications", page 26
Table 7: DC

1 = BN + (L+)
2 = WH Q2 / IN
3 = BU - (M)
4 = BK Q1 / C
5 = GY Q3
