Absolute & Incremental Linear Encoders

Linear encoders sense and digitize linear position change for position measurement and feedback to control systems. They convert linear motion into electrical signals, ensuring accuracy and repeatability in high-performance applications.

Linear encoders are available in two types, absolute and incremental, as defined by their position signals.  Absolute linear encoders create a unique position signal that is available anywhere along travel. The exact position will be read after power cycling. Incremental encoders do not generate a unique signal. The encoder is zeroed after power-down and relies on another switch or encoder for initial reference.  

Linear encoders are critical components in motion control, providing precise position feedback for automation, CNC machining, robotics, and semiconductor manufacturing.
