6 Electrical installation
Operation in standard I/O mode:
The sensors must be connected in a voltage-free state (U
V
= 0 V). The following informa‐
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
V
> 0 V) once all electrical connec‐
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
www.sick.com
under the part number.
Explanation of connection terminology used in Tables 1-3:
BN = Brown
WH = White
BU = Blue
BK = Black
n. c. = no connection
Q1 = switching output 1 / IO Link Communication
Q2 = switching output 2
L+ = supply voltage (Uv)
L1 = AC supply voltage
M = common
N = AC common
Test = Test input
L.ON = light switching
D.ON = dark switching
NOTE
The sensor outputs may come equipped with an adjustable ON delay or OFF delay. This
is indicated by the model configuration (Hx18-xxxxx_).
