  • Limit Switches

    Limit Switches

    Limit switches are used to convert a mechanical motion into an electrical control signal. The mechanical motion is usually in the form of a cam, a machine component or an object moving toward a pre-determined position. The cam engages the limit switch lever or plunger which makes or breaks an electrical contact inside the switch. This electrical control signal is then used to limit position or reverse the machine travel or to initiate another operating sequence. It can also be used for counting, sorting or as a safety device.

  • Magnetic Proximity Switches

    Magnetic Proximity Switches

    Non-contact proximity switches are used to detect the position of mechanical motion and provide accurate position indication. An actuator, in the form of a target magnet, passes in front of the proximity switch, engaging the switch, and allowing the internal electrical contacts to change state. The application is never in physical contact with the proximity switch. Applications that typically use limit switches include valve position indication, sorting, level detection and many safety related situations.
