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

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 (see separate Product Information sheet).

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 interferentially scanned. This makes it possible to measure positions in a plane.

Mechanical design

Exposed linear encoders consist of a scale or scale tape and a scanning head that operate without mechanical contact. The scale of an exposed linear encoder is fastened directly to a mounting surface. The flatness of the mounting surface is therefore a prerequisite for high accuracy of the encoder.
