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.
