Product Description
The BUS M12M1 sensor offers a
non-contact measurement of the dis-
tance to an object that has to be pre-
sent within the sensor’s detection
zone. Depending on the set window
limits, a distance-proportional ana-
logue signal is output.
The window limits of the analogue
output and its characteristic can be
adjusted with the Teach-in proce-
dure.
One 2-colour LED indicates operation
and the state of the analogue out-
put.

detection zones
for different objects:
The dark grey areas are determined with a
round bar and indicate the typical operating
range of a sensor. In order to obtain the light
grey areas, a plate (100 x 100 mm) is
introduced into the beam spread from the side.
In doing so, the optimum angle between
plate and sensor is always employed.
This therefore indicates the maximum
detection zone of the sensor.
It is not possible to evaluate ultrasonic
reflections outside this area.

Safety Notes
Read the operating instructions
prior to start-up.
Connection, installation and
adjustment works should be car-
ried out by expert personnel only.
No safety component in
accordance with the EU Machine
Directive
Use for intended purpose only
BUS M12M1 ultrasonic sensors are
used for non-contact detection of
objects.
Installation
Mount the sensor at the installa-
tion site.
Connect a connection cable to the
M12 device plug.
The assembly distances shown in fig.

be fallen below in order to avoid mu-
tual interference.

Maintenance
Balluff sensors are maintenance-free.
In case of excess caked-on dirt we
recommend to clean the white sen-
sor surface.
Notes
Every time the power supply is
switched on, the sensor detects its
actual operating temperature and
transmits it to the internal tempe-
rature compensation. This results
in a slight correction of the ana-
logue output value after 45 se-
conds.
If the sensor was switched off for
at least 30 minutes and after po-
wer on an object is placed in the
middle of the adjusted analogue
window for 30 minutes (the ana-
logue output value is in the range
of 11 to 13 mA or 4.4 to 5.6 V) a
new adjustment of the internal
temperature compensation to the
actual mounting conditions takes
place.
The sensors of the BUS M12M1
family have a blind zone. Within
this zone a distance measurement
is not possible.
In the normal operating mode, an il-
luminated yellow LED signals the ob-
ject is within the adjusted window
limits.
The sensor can be reset to its fac-
tory setting (see »Further set-
tings«).
Enclosure Type 1
For use only in industrial
machinery NFPA 79 applications.
The proximity switches shall be used with a Listed (CYJV/7) cab-
le/connector assembly rated minimum 32 Vdc, minimum 290
mA, in the final installation.
