HEIDENHAIN Exposed Linear Encoders
Touch-free measurement for high-precision motion
An exposed linear encoder is a scale or scale tape plus a separate scanning head. HEIDENHAIN's photoelectric scanning is touch-free and wear-free, reading graduation lines just micrometers wide for very short signal periods and high accuracy.

How to choose
Absolute or incrementalAbsolute encoders (LIC) know their position at power-up. Incremental encoders (LIP, LIF, LIDA) count from a reference mark.AbsoluteIncremental
AccuracyLIP 200 and LIP 6000 offer very high accuracy and high traversing speeds; LIF 400 adds adhesive scale fastening with limit switch and homing track.Very high accuracy
Length and mountingLIC 4100, LIC 3100 and LIDA 400 cover long measuring lengths with different mounting options.Long measuring lengths
Easy installationLIC 2100 and LIDA 200 have wide mounting tolerances; LIDA 200 has an integrated signal-quality indicator.Easy installation
