CIRCUIT DIAGRAM
OPERATING PRINCIPLE
MC 346 magnetic contact has two parts: the contact part
with a reed switch and the magnet part. In its neutral
position the reed switch remains closed under the force of
the magnetic field. Opening the monitored object increases
the distance between the reed switch and the magnet. This
causes a change in position of the reed switch and as a result
– a path of the signal.
Magnetic contacts should not be installed in the vicinity of
strong magnetic fields.
