Description
Heidenhain LIF 10R Linear Encoder Scanning Head w/ Interpolator 295 621 03
The Heidenhain LIF 10R is a photoelectric incremental linear encoder scanning head designed to work with Heidenhain exposed linear glass scales. The system consists of two main components: a compact scanning head with a large-aperture optical lens that reads the linear scale, and a separate interpolator electronics unit connected by cable, which conditions and outputs the position signal. The assembly connects to downstream CNC controls or measuring systems via a circular multi-pin connector.

Applications
The Heidenhain LIF series encoders are used in precision linear positioning and measurement applications, most commonly in CNC machine tools (milling machines, machining centers, lathes, and grinding machines) where direct linear feedback — rather than rotary encoder feedback through a ballscrew — is required for the highest positioning accuracy. The scanning head reads a stationary glass scale affixed to the machine bed or axis, delivering incremental position data to the CNC control in real time. LIF-type encoders are also found in coordinate measuring machines (CMMs), semiconductor manufacturing equipment, precision test stages, and other metrology or automation systems where sub-micron positioning feedback is critical. Heidenhain has been a leading manufacturer of precision encoder systems for decades, and the LIF 10R is a mid-generation exposed linear encoder compatible with the Heidenhain ecosystem of controls and interpolation electronics.
This Heidenhain LIF 10R linear encoder scanning head has been pulled from a working environment and visually inspected. The assembly includes the scanning head with its optical lens, the interpolator electronics unit, and the full cable with circular multi-pin connector — all appear intact and show only light handling wear consistent with normal use. The label on the interpolator body is fully legible (Id.Nr. 295 621 03). No obvious physical damage is noted.
