One Inch Can-Stack Linear Actuator Has Proximity Sensor
A highly repeatable on/off signal is accomplished using a rare earth magnet embedded directly on the end of the internal screw. As the screw moves in and out of the actuator, the magnet moves toward and away from the sensor face causing the device to switch states. The proximity sensor is designed to operate in a digital switch mode using an open-collector output through an integrated NPN transistor switch. The proximity switch is a three wire device and requires a supply voltage of 3.8 VDC minimum to 24 VDC maximum with a current consumption of 10 mA max.
