Heidenhain Brand Logo

ISC Companies and ISC Automation can supply the Heidenhain products listed on this page and others found on the Heidenhain website. For more information or for a product quote, please contact us by phone 763-559-0033, by email [email protected], or by filling out our online contact form.

Heidenhain products include linear and angular encoders, rotary encoders, digital readouts, and numerical controls for applications where the highest possible accuracy, reliable reproducibility, and repeatability are required. Heidenhain products are primarily used in high-precision machine tools, in plants for the production and processing of electronic components, and in automated systems and machines.

Length Measurement

Heidenhain Linear EncodersLinear Encoders (Sealed/Exposed) & Length Gauges

Incremental linear encoders determine current position by starting at a datum and counting measuring steps, or by subdividing and counting signal periods. Absolute linear encoders require no previous traverse to provide the current position value.

Heidenhain sealed linear encoders are protected from dust, chips, and splash fluids and are ideal for operation on machine tools. Heidenhain exposed linear encoders operate with no mechanical contact between the scanning head and the scale or scale tape. Applications include measuring machines, comparators, precision devices, and production equipment used in the semiconductor industry. Heidenhain length gauges feature integral guideways for the plunger and are used to monitor measuring equipment, in industrial metrology, and as position encoders.

  • LC, LF, LS, LB Sealed Linear Encoders with full-size scale housing have a high tolerance to vibration
  • LC, LF, LS Sealed Linear Encoders with slimline scale housing are used where installation space is limited
  • LIP, LIF Exposed Linear Encoders are characterized by small measuring steps together with very high accuracy
  • LIC, LIDA Exposed Linear Encoders are for high traversing speeds and large measuring lengths
  • PP Exposed Linear Encoders two-coordinates with a planar phase-grating structure on a glass substrate
  • AT, CT, MT, ST Length Gauges are characterized by high accuracy with large strokes
