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 nonmagnetizable metals, they detect a permanent
magnet attached to the piston through the
aluminium cylinder wall.
Weld-field immune permaprox sensors "freeze"
the switching status when detecting a magnetic
AC field (50…60 Hz). In this way, false
switching operations are prevented during the
welding process. When the AC field disappears,
the sensors resume standard operation.
