Integrated Switch Increases Versatility of the 25mm Can-Stack Linear Actuator
Alongside precision couplings, gears and intelligent motion control, Reliance Precision Mechatronics, the UK distributor for Haydon Kerk Motion Solutions Inc., a leading manufacturer of precision linear motion products, now offers an integrated end-of-stroke proximity sensor available on the 25mm 25000 Series captive linear actuators. The proximity sensor utilises miniature hall effect technology in an IC package mounted directly on the actuator. The hall effect is an ideal technology with a virtually unlimited on-off cycle life due to the non-contact operation of the switch. The Can-Stack linear actuator with the integrated proximity sensor is perfect for limited space applications.
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 towards 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 3 wire device and requires a supply voltage of 3.8 VDC minimum to 24 VDC maximum with a current consumption of 10mA max.
The Haydon 25000 Series is part of the G4 line of high-output Can-Stack linear actuators and are "second to none" in performance when compared to similar sized actuators in the marketplace today. Improvements include optimized stator tooth geometry, high energy neodymium magnets, custom engineered polymers, and larger ball bearings for greater rotor support and axial loading.
