EMAX / EMAL Magnetic Length Measuring System

Magnetic length measuring system with distance detection

  • Absolute measurement
  • Resolution 0.01 mm
  • No calibration necessary – changes of position are also recognised in zero-current period
  • With LED and SSI error-bit in case of too large distance sensor-tape
  • Measuring length up to 10 m (EMAX), 20 m (EMAL)
  • Incremental square- or sine-cosine signals for dynamical movement control
