Encoders

Encoders, also known as rotary encoders or shaft encoders, are sensor devices that convert motion or position into an analog or digital signal. These feedback devices are employed in a wide array of applications, including industrial controls, robotics, photographic lenses, computer input devices, and many more.

Whether you require incremental encoders for monitoring relative position changes or absolute encoders for tracking an object's absolute position, our range is designed to cater to your unique needs. We provide models in various sizes, resolutions, and output formats, ensuring we can meet the requirements of every project.
