Heidenhain - Exposed Linear Encoder - LIP - LIF - LIC

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


LIP/LIF/LIC - For application in high and ultrahigh vacuum technology
Incremental Encoders

Our standard encoders are suitable for use in a low or medium vacuum. Encoders used for applications in a high or ultrahigh vacuum need to fulfill special requirements. Design and materials used have to be specially adapted for it. For more information, refer to the Technical Information document Linear Encoders for Vacuum Technology.
The following exposed linear encoders are specially adapted for use in high and ultrahigh vacuum environments.

  • High vacuum: LIP 481 V and LIF 481 V
  • High vacuum: LIC 4113 V and LIC 4193 V
  • Ultrahigh vacuum: LIP 481 U
