Carlo Gavazzi offers a comprehensive range of Magnetic Sensors to be used in proximity of detection applications.
They are employed 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.
Moreover, the output will be a mechanical contact.
There is a wide variety of styles available including rectangular, cylindrical, and slotted ones. In addition, 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.
