HEIDENHAIN Sealed Linear Encoders
Precise position for every machine axis
A linear encoder measures the position of a machine slide directly and sends it to your control or readout. HEIDENHAIN sealed linear encoders have an aluminum housing that protects the scale, scanning carriage, and guideway from chips, dust, and splash water, with sealing lips below and a coupling that compensates for misalignment.

How to choose

Absolute or incrementalAbsolute encoders (LC) know their position at power-up. Incremental encoders (LS, LB) count from a reference mark.AbsoluteIncremental


Measuring lengthFor long axes choose LC 200 (absolute, up to 28 m) or LB 383 (incremental, up to 72 m).Long measuring lengths

Functional safetyLC 100 and LC 400 are also available in functional safety versions.

Interface and accuracyMatch the interface your control or readout expects, and tell us the measuring length and accuracy grade you need.
