Linear encoders are used for non-contact length measurement and position determination. A read head scans a code pattern or the magnetic field of a magnetic scale and outputs the corresponding electric signal.

Code patterns allow rotary or linear encoders to monitor position, angle, and speed. The tick marks or codes are inscribed as digital patterns on a glass, metal or plastic disc. These marks or codes are scanned using a light source. Encoders with optical scanning typically have higher resolutions than magnetic encoders.

For position determination, linear encoders require measuring elements that must be installed along the entire measuring path. The code pattern is formed by different magnetizations that are scanned by magnetic sensors in the read head.

Position, angle and speed monitoring for rotary or linear encoders using LEDs, code patterns and photodiodes. The tick marks (on incremental encoders) or codes (on absolute encoders) are inscribed as digital patterns on a glass, metal or plastic disc and are scanned using a light source (light emitting diode) and photo-diodes. Encoders with optical scanning typically have higher resolutions than encoders that use magnetic scanning.

Position, angle and speed monitoring for rotary or linear encoders using permanent magnets and corresponding evaluation units to measure the magnet field. Encoders with magnetic scanning typically have lower resolutions than encoders that use optical scanning.
