Function
The magnetic switch has two bistable contacts. The reed contacts are switching when
the front sides of the actuator and the sensor
are approached to one another. The actuating
diagrams show the switching behaviour with
different actuators.
If the BP 310-1S actuator is approached to the
magnetic switch in accordance with the actuating diagram, the reed contacts will close. The
contacts will remain closed, if the actuator is
passed on beyond the active zone of the magnetic switch. If the actuator is re-approaching
the magnetic switch from the opposite direction, the reed contacts will open.
Tolerances in the monitored mechanical movement are compensated by this latching behaviour and do not cause undesired switching
functions.
In concealed mounting and in combination with
an appropriate safety-monitoring module, the
magnetic switch can be used for safety applications. The aforementioned configuration
complies with the requirements of
IEC/EN 60947-5-3, PDF-M.
The switching distances of the different actuators are listed in the technical data.
