Heidenhain LS 406 Incremental Linear Encoder Module

The Heidenhain LS 406 Incremental Linear Encoder Module is a compact linear position sensor that provides incremental position information over a 120 mm measuring length. As a linear scale encoder, it converts linear motion into relative-position signals that are used by a readhead and controller for closed-loop positioning. The module lists a 120 mm measuring length and a 20 µm specification, making it suitable for short-travel axes in CNC machines, automation equipment, metrology setups, and other precision positioning tasks where compact size and repeatable incremental measurements are required. Typical applications include machine tool slides, positioning stages, and automation actuators that demand reliable linear measurement within a fixed span. When integrating this module, ensure compatibility with your control system and readhead.
