Principle of oper‐
ation
Mode Description
MultiMode 1
(LED 1)
Background sup‐
pression (BGS)
The sensor reliably detects objects no
matter whether there is a background
or not.
MultiMode 2
(LED 2)
Foreground sup‐
pression
The sensor detects objects in front
of the background with a small dis‐
tance between object and background.
It requires a stable background as a ref‐
erence.
The sensor is typically used to detect
flat objects on conveyor belts.
MultiMode 3
(LED 3)
Background sup‐
pression (BGS)
Two Value Teach-
in (BGS)
The sensing range is defined by teach‐
ing in at two points (object leading
edge/rear edge). The sensing range is
placed in the center of the two distan‐
ces.
MultiMode 4
(LED 4)
Background sup‐
pression (BGS)
Two independent
switching points
(BGS)
The sensor has two independent switch‐
ing points that can be taught in sepa‐
rately.
MultiMode 5
(LED 5)
Background sup‐
pression (BGS)
Window (BGS) The sensor detects objects located
within a taught-in window.
MultiMode 6
(LED 1+6)
Background sup‐
pression (BGS)
ApplicationSelect Sensing range increases. The sensitiv‐
ity increases so that even shiny, dark
and uneven objects, even in an inclined
position, are reliably detected.
MultiMode M
(LED 7)
INDEPENDENT Manual/Meas‐
urement
With “Manual/Measurement” mode, the
distance value can be read out via IO-
Link. This mode is only available via IO-
Link.
A description of the IO-Link parameters
can be found in the IO-Link description:
