Options and special informationFunctional description
Magnetic switches respond to magnetic fields. In the sensor, two shielded and two non-shielded resistors are combined with a bridge connection. In case of presence of a magnetic field, a large signal will be obtained, which is proportional to the size of the magnetic field. Starting from a certain threshold, an output signal is switched via a comparator, and the sensor responses.
Signal output and switching type
The sensors are available in a design with signal output of closer and in the switching types PNP (J02P) and NPN (J02N).
Versions with connector or cable end
The sensor is available in the versions with a plug connector (30 cm cable, M8 connector) or open cable outlet (2 m cable, open strands).
Sources of interference
Sensors can be influenced by other magnetic fields in the immediate vicinity. Disturbing magnetic fields can be generated by motors, electric welders, permanent magnets or magnetized material (so-called soft magnets) such as hexagon socket wrenches, chips, etc.
