Retroreflective sensor
with 4-pin, M8 x 1 connector
Features
• Reliable sensor for standard applicati-
ons
• Miniature design with versatile moun-
ting options
• Reliable recognition of reflective ob-
jects and clear glass
• Two machines in one: clear object de-
tection or reflection operating mode
with long range
• TEACH-IN switch for setting the cont-
rast detection levels
• Automatic adjustment in case of soi-
ling in contrast detection mode
Product information
Small, robust, effective, and reliable - these
are the properties of the ML7 sensor series.
Due to their small size, number of versions,
and two different lens positions, they are par-
ticularly suited for installation in tight spaces.
The robust design and high quality of Pep-
perl+Fuchs mean they can also be used
under harsh environmental conditions. The
efficient technology, switching frequencies up
to 1000 Hz, high resistance to ambient light,
and 4-in-1 output make the series suitable for
non-contact object detection.

1 N on flashes 4/s In switch position "N" directed towards
reflector.
Reflector detected without function
reserve.
N on on - In switch position "N" directed towards
reflector.
Reflector detected with function reserve
(recommended).
2 T off/on on 200 ms The selection of a new switch position is
indicated by the green LED going out for a
short time.
This also applies to the selection of the other
switch positions.
T flashes flashes 2.5 s Slow alternating flashing: Teach-In process
has been performed correctly.
Max. duration of the Teach-In process: 2 s
T flashes flashes 8/s Quick alternating flashing: Teach-In process
has not been performed correctly. (e.g.
receiver signal not sufficient, sensor not
directed correctly towards reflector).
Status is terminated by turning switch to
position N.

clean PET bottles filled with water)
3/2 II on on - Contrast detection 18% is activated. (e.g.
clear glass bottles)
