Haydon Kerk 25000Haydon Kerk Motion Solutions now offers an integrated end-of-stroke proximity sensor available on its 1-inch 25000 Series captive linear actuators. The solution further incorporates:

  • Miniature hall effect technology in an integrated circuit package mounted directly on the actuator.    
  • A highly repeatable on/off signal, which is accomplished using a rare earth magnet embedded directly on the end of the internal screw, with a virtually unlimited cycle life due to the non-contact operation of the switch. 
  • The ability to operate in a digital switch mode using an open-collector output through an integrated NPN transistor switch. 
  • A 3-wire proximity switch that requires a supply voltage from 3.8 to 24 VDC with a current consumption of 10 mA. 
  • Optimized stator tooth geometry.
  • High-energy neodymium magnets.
  • Custom-engineered polymers.
  • Larger ball bearings for greater rotor support and axial loading. 
  • Suitability for limited space applications.
