直接驱动 Absolute encoders and encoders with position value outputSeries | Description | Position error
per signal period | Measuring length |
|---|
 LIC
| The LIC exposed linear encoders permit absolute position measurement both over large paths of traverse up to 28 m and at high traversing speed. In their dimensions and mounting, they match the LIDA 400. | ± 0.08 µm | Up to 28440 mm |
|---|
LIP 200 | The LIP 211 and LIP 291 incremental linear encoders output the position information as a position value. The sinusoidal scanning signals are highly interpolated in the scanning head and converted to a position value by the integrated counter function. As with all incremental encoders, the absolute reference is determined with the aid of reference marks. | ± 0.001 µm | Da 20 mm a 3040 mm |

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. | Up to ± 0.04 µm | Up to 3040 mm |
|---|
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). | ± 0.04 µm | Up to 1020 mm |
|---|
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. | Up to ± 0.2 µm | Up to 30040 mm |
|---|
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. | ± 0.04 µm | Measuring range 68x68mm |
