Limit Switches

Our limit switches are electro-mechanical devices that consist of an actuator mechanically linked to a set of contacts. When an object comes into contact with the actuator, the device operates the contacts to make or break an electrical connection. Our limit switches work in a variety of applications and environments because of their ruggedness, simple visible operation, easy installation and reliable operation.

Condition Sensing Devices

Our condition sensing devices communicate process variable information to automatically sequence equipment or provide a signal to operators for manual operation. Featuring electromechanical and solid-state solutions, our condition sensors can lower your total operating costs by helping to improve processes and systems, reduce downtime, protect expensive equipment and safeguard operators.

Encoders

Encoders can electronically monitor the position of a rotating shaft. Our absolute encoders on EtherNet/IP connect to and operate with the Logix controllers to provide position tracking data to be used in open-loop control systems. Our absolute encoders are electro-mechanical devices that are useful feedback elements in closed-loop control systems. They provide position control in packaging, robotics, pick and place, lead/ball screw, rotary table positioning and component insertion applications. Our Incremental Optical Encoders provide low cost, smaller physical size, high frequency and high resolution. Our accessories help you easily install and efficiently use our encoders.
