Heidenhain - Exposed Linear Encoder - PP
Exposed linear encoders are designed for use on machines and installations that require 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
PP - For two-coordinate measurement
Incremental Encoders
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.
