Heidenhain - Exposed Linear Encoders

Exposed linear encoders are designed for use on machines and installations that require especially high accuracy of the measured value.

Typical applications include:

  • Measuring and production equipment in the semiconductor industry
  • PCB assembly machines
  • Ultra-precision machines
  • High-accuracy machine tools
  • Measuring machines and comparators, measuring microscopes, and other precision measuring devices
  • Direct drives

 

Absolute position measurement

Series

Description

LIC The LIC exposed linear encoders permit absolute position measurement both over large paths of traverse up to 27 m and at high traversing speed. In their dimensions and mounting, they match the LIDA 400.
LIP 200 The LIP exposed linear encoders are characterized by very small measuring steps together with very high accuracy and repeatability. They operate according to the interferential scanning principle and feature a DIADUR phase grating as the measuring standard.

Incremental linear measurement
 

Series

Description

LIP

The LIP exposed linear encoders are characterized by very small measuring steps together with very high accuracy and repeatability. They operate according to the interferential scanning principle and feature a DIADUR phase grating as the measuring standard.

LIF

The LIF exposed linear encoders have a measuring standard manufactured in the SUPRADUR process on a glass substrate and operate on the interferential scanning principle. They feature high accuracy and repeatability, are especially easy to mount, and have limit switches and homing tracks. The special version LIF 481 V can be used in high vacuum up to 10–7 bar

LIDA The LIDA exposed linear encoders are specially designed for high traversing speeds up to 10 m/s, and are particularly easy to mount with various mounting possibilities. Steel scale tapes, glass or glass ceramic are used as carriers for METALLUR graduations, depending on the respective encoder. They also feature a limit switch.  
PP On the PP two-coordinate encoder, a planar phase-grating structure manufactured with the DIADUR process serves as the measuring standard, which is scanned interferentially. This makes it possible to measure positions in a plane.
