HEIDENHAIN LIP 481 Exposed Linear Encoder | Configuration Inquiry
The HEIDENHAIN LIP 481 is an incremental exposed linear encoder documented for high-accuracy measurement in limited installation space. This page is for configuration, repair, replacement, or sourcing inquiries. Availability and the right service path depend on the exact part and application; please contact AMI for an assessment rather than assuming a unit is in stock or currently produced.
- Historical HEIDENHAIN documentation specifies 1 VPP analog incremental signals, a 2 µm signal period, and a 4 µm grating period.
- Documented measuring lengths are 70 to 420 mm, with a nominal ±1 µm accuracy grade; options and higher grades vary by part.
- The measuring standard may be Zerodur glass ceramic or glass. Reference-mark and no-reference-mark versions are documented. Confirm the exact part number, length, scale material, reference marks, connector, and mounting arrangement before ordering or service.
HEIDENHAIN technical information for exposed linear encoders (PDF) covers the LIP 481 family. The image and configuration details on this page are drawn from HEIDENHAIN's historical exposed-linear-encoder catalog; specifications must be checked against your exact unit.
Request a quote or assessment with the LIP 481 part number, a label photo, measuring length, and a brief description of the repair, replacement, or sourcing need. AMI will confirm what options can be offered.
