EMAX-HI Absolute Measuring System Magnetic high-resolution linear encoder for dynamic processes

High-resolution magentic measuring system for absolute position measurement in dynamic applications. Ideally suited in linear drives.

  • High-resolution - up to 1 µm
  • Operation speed up to 10 m/s
  • For measuring lengths up to 8 m
  • Standard interfaces: SSI, CANopen (DS406) or RS422
    on request: CAN BASIC ELGO or BISS-C
  • Additional incremental square-wave signals (A, B) or analog signal output Sin/Cos (1 Vss) in real-time for highly dynamic control (option)
  • High safety during installation and operation by visual (LED) and signal output error message in case the max. allowable reading distance to scale is exceeded
  • Typical applications: linear actuators, pick&place, medicine technology
