Heidenhain LC 195F is one of the closed-loop linear encoder series introduced by Heidenhain, belonging to the LC 195 F family. Its main technical features are as follows:

Measurement range: Available measuring lengths from 140 mm to 4,240 mm (the maximum length depends on the grating pitch). Common specifications include 640 mm, 840 mm, 1,040 mm, 1,340 mm, 1,740 mm, 2,240 mm, 3,240 mm, etc.
Resolution: Multiple resolutions are available, including 10 nm, 12.5 nm, and 50 nm. Typical configurations are 10 nm (αi interface) or 50 nm (α interface).
Supply voltage: DC 3.6–14 V, compatible with various CNC systems such as Fanuc 05 and Panasonic Pana01.
Interface types: Supports multiple industrial interfaces, including αi, α, Fanuc 05, and Panasonic Pana01, allowing direct integration into machine tools and automation equipment.
Accuracy grade: ±3 μm (some variants specified as ±5 μm), meeting the requirements of high-precision machine tools and automated assembly systems.
Structural features: Closed-type design with dual sealing, providing effective protection against dust and chips, good vibration resistance, and suitability for harsh industrial environments.

Applications

The LC 195F is mainly used in CNC machine tools, automated production lines, and semiconductor and electronics manufacturing equipment where high-resolution, long-travel linear position measurement is required. The combination of high resolution and wide measuring range enables sub-micron positioning accuracy in large-span machining centers or multi-axis machine tools.

Selection Recommendations

• Determine travel requirements: Select the appropriate length model according to the machine’s maximum travel (e.g., 1,040 mm, 2,240 mm, 3,240 mm, etc.).
• Resolution requirement: For extremely high machining accuracy (micron or sub-micron level), 10 nm resolution is recommended; for general industrial machining, 50 nm is sufficient.
• Interface compatibility: Verify the signal interface used by the CNC system and select the corresponding αi, α, Fanuc 05, or Panasonic Pana01 interface.
• Environmental conditions: In environments with heavy dust, chips, or coolant, a dual-sealed version (such as LC 195P) is recommended to enhance reliability.
