Magnetic and electronic proximity sensors
sensors mounted onto the cylinders detect the position of
the piston by commutating an electric signal when approaching
the magnetic field produced by the magnet incorporated in
the piston itself.
They are manufactured using two different technologies: electromechanical with Reed bulb; electronic with magnetoresistive effect (normally open with PNP output); upon request with NPN output.
The first one with Reed bulb function both in d.c. and a.c.; the second ones, electronic type function only in d.c. 30V max. In both versions the active status is indicated by the lighting of a luminous diode.
