Overview

LF11 is a board-level absolute linear magnetic encoder system designed for motion control applications as a position and velocity control loop element.

The miniature design and low weight of the encoder system make it suitable for applications with limited space in relatively clean environments.

Features

  • True absolute system
  • Small footprint 50 × 12 × 5 mm
  • Resolutions up to ~0.244 μm
  • Axis lengths up to 16.3 m
  • BiSS C unidirectional

Benefits

  • Suitable for highly dynamic control loops
  • Speeds up to 7 m/s at 0.976 μm resolution
