Linear encoders consist of a read head (sensor) and a reference scale (measuring element). The non-contact principle of operation means that the position is determined without wear. The sensor uses a unique code pattern to record the absolute position information along the reference scale, and sends this information directly to the evaluation electronics. As a result, there is no need for a reference run. Compact systems with high resolutions or rugged solutions with very high measuring lengths (up to 1,700 m) can be used in a wide range of applications.
