Haydon KerkMotion Solutions Inc.'s integratedend-of-stroke proximity sensor is available on the one inch 25000 Seriescaptive linear actuators. The proximitysensor utilizes miniature hall effect technology in an IC package mounteddirectly on the actuator. The halleffect is a technology with a virtually unlimited on-off cycle life due to thenon-contact operation of the switch. TheHaydon can- stack linear actuator with the integrated proximity sensor is usefulfor limited space applications.

A highly repeatable on/off signal isaccomplished using a rare earth magnet embedded directly on the end of the internalscrew. As the screw moves in and out ofthe actuator, the magnet moves toward and away from the sensor face causing thedevice to switch states. The proximitysensor is designed to operate in a digital switch mode using an open-collectoroutput through an integrated NPN transistor switch. The proximity switch is a 3 wire device and requiresa supply voltage of 3.8 minimum to 24V dc maximum with a current consumption of10mA max.
