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.

48CR Code Reader

Our code readers are the smallest industrial code readers on the market. These rugged, compact solutions can decode 1D, 2D and Direct Part Marked (DPM) codes and they can even successfully read damaged and incomplete symbols. The 48CR supports Ethernet/IP™ and can be configured through either the Studio 5000 Logix Designer application Add-on Profile (AOP) or the embedded WebConnect visual browser.

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.

Absolute Encoders

Absolute encoders retain your position data during loss of power. They are excellent choices in systems that require failsafe operation. Our magnetic encoders directly connect to DeviceNet™ for advanced functionality with reduced wiring cost. Our sine/cosine encoders provide absolute feedback for position control and high resolution incremental feedback for speed control. Our Integrated Motion on EtherNet/IP encoders leverage CIP Sync, a time synchronization extension that is fully compliant with IEEE 1588. You can use our single-turn encoders for reliable readouts in harsh conditions.

Incremental Optical Encoders

Our incremental optical encoders produce digital output related to the position of a rotating shaft, providing feedback elements in closed-loop control systems. You can use our encoders with external electronics, such as counters, to accumulate data to determine position, speed, and direction. Use these encoders when position retention is not required during a loss of power.
