Technical Info -
offers a comprehensive range of magnetic sensors for use in proximity
detection applications. As their name suggests, they used in conjunction
with an external magnet - when the sensor approaches the magnet, the
output from the sensor will change state.
Typically these sensors
will have a longer sensing distance than typical proximity sensors.
As well, the output will be a mechanical contact.
There are a wide variety of styles available including rectangular,
cylindrical, and slotted. As well, special coded magnets and sensors
are available for use in safety applications. Magnetic sensors are
frequently used on elevators and lifts, gate control, level detection,
and access control.
