Wiring Diagram
Functional principle
Magnetic field sensors are activated by magnetic fields and are used, in particular, for the
detection of the piston position in pneumatic
cylinders. As magnetic fields can permeate
non-magnetizable metals, they detect a permanent magnet attached to the piston through
the aluminium cylinder wall.

Mounting instructions/Description Mounting instructions
Insert the sensor laterally in the groove with the tip first.
Once the correct postion is attained click the sensor in
the groove. Finally, screw the sensor tight. Mount the
sensors as follows using the patented wing screw: The
wing screw features a left-hand female thread. Two
small plastic lips keep the screw in position, ready-to-
install. Turn the screw clockwise. The screw moves out
of the thread and hits the upper grooves with the wings.
The sensor is thus pressed down and locked. Use a
standard screw driver or a 1.5 mm Allen key to fasten
the screw with a quarter turn. A fixing torque of 0.4 Nm
is sufficient for safe mounting without damaging the
cylinder. Mounting accessories for other cylinder sizes
have to be ordered separately.
