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.
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_).
