Heidenhain LC495F ML 270mm Scale 12.5/50nm

The LC495F-270MM from HEIDENHAIN is a high-precision sealed linear encoder designed to provide accurate position feedback for CNC machine axes. Part of the LC495F series, it is commonly used on machining centers, CNC lathes, and grinding machines where reliable closed-loop control and high positioning accuracy are essential.

Designed for demanding machine-tool environments, the LC495F features a sealed construction that protects the measuring system from coolant, chips, vibration, and other contaminants. By delivering stable, high-resolution position data to the CNC control, it helps ensure precise axis movements, consistent machining quality, and excellent repeatability during both roughing and finishing operations.

With a measuring length of 270 mm and fine resolution options of 12.5 nm/50 nm, depending on the interface and signal subdivision, this encoder supports tight contouring and smooth interpolation on modern CNC systems. It is typically installed within protected axis covers and integrated into machines using compatible HEIDENHAIN feedback interfaces.

The LC495F-270MM is frequently used as a replacement or retrofit component to correct positioning errors, encoder alarms, following faults, or homing inconsistencies caused by damaged scales or contaminated scanning systems. Manufactured in Germany, it is valued for its durability, accuracy, and long service life in industrial applications.

For replacement projects, it is important to verify the measuring length, mounting dimensions, interface type, cable configuration, connector style, and scanning head arrangement to ensure full compatibility with the existing installation. Its reliability and precision make it a popular choice for maintenance teams seeking to reduce downtime and maintain the performance of CNC equipment.
