END OF STROKE SWITCHES AND SENSORS

 
Home Position Switch
 

Haydon offers a miniature electronic switch capable of monitoring the home positions of linear actuators.

The home position switch mounts on the rear sleeve of Haydon’s captive linear motors. This allows the user to identify start, stop or home postions of the actuator.

Depending on your preference, contacts can be normally open or normally closed. The contact closure is repeatable to within one step position, identifying linear movements as low as 0.0005" (0.0013 cm) per step. Multiple contact switches are also available.

The switch allows device manufacturers the ability to monitor movements more precisely for greater control and improved Q.C. When ordering motors with the home position switch, the part number should be preceded by an S. Contact Haydon Kerk Motion Solutions for additional ordering information.

End of Stroke Proximity Sensor
 

Haydon offers a miniature hall effect sensor capable of monitoring the end position of linear actuators.

The sensor incorporates a hall effect device, which is activated by a rare earth magnet embedded in the end of the internal screw. The compact profile of the sensor allows for installation in limited space applications.

The sensor has virtually unlimited cycle life.  Special cabling and connectors can be provided.

Haydon's end of stroke proximity sensor, and all Haydon Kerk Motion Solutions products are backed by a technical team which provides extensive customer support and applications assistance.

Suggested Interface Diagrams:
Note: Sensor is category 2 ESD sensitive per DOD-STD-1686A. Assembly operations should be performed at workstations with conductive tops and operators grounded.

PLEASE NOTE THAT A PULL-UP RESISTOR IS REQUIRED FOR THE SENSOR TO OPERATE CORRECTLY.
