EMAX-HI High-Resolution Magnetic Absolute Linear Sensor

High-resolution magnetic absolute sensor for use in dynamic processes

  • High-resolution – up to 1 µm
  • Operation speed up to 10 m/s
  • For measuring lengths up to 8 m
  • Interfaces: SSI, CANopen
  • 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 application: linear actuators, pick & place, medicine technology
