– TECHNICAL USER GUIDE
PRODUCT DESCRIPTION:
MS 44R is a capacitive relay sensor for
detection of feed, grain and solids. The
sensors have relay output including switch
function.
Fields of application:
• Start/Stop for supply of materials.
MOUNTING GUIDE (FIG. 1):
• Use the supplied cable ties to mount the
sensor on the feed line. The sensor only
works if mounted on ø40-60 mm plastic
pipes.
• The sensor needs to be in direct contact
with the plastic pipe. This can be verified be
checking that the edge of the sensor is flush
with the lower edge of the bracket.

INSTALLATION GUIDE (FIG. 2):
Supply voltage is connected to the blue and
brown wire.
The load is connected in series with the relay
contact of the sensor.
STOP
by activating the sensor: Use the black
wires 1 and 3.
START
by activating the sensor: Use the
black wires 1 and 4.
NOTE!
The internal relay is in position NC
when the supply voltage is connected and the
sensor is activated - wire 1 and 4 are
connected.
