EMAX with IO-Link magnetic abolute measuring system with integrated io-link interface

EMAX-IO combines the advantages of the proven absolute magnetic tape measuring system EMAX and the currently most popular interface in the control world. The integrated IO-Link interface enables reliable, flexible information exchange and data transport from the IO-Link master to the end device. EMAX-IO delivers the absolute position over a distance of up to 20 m and with a resolution/repeat accuracy of 10 µm via a 3-wire cable. Further advantages are safe transmission, continuous diagnostics and fast installation, as the sensor can be parameterized from a central location.

  • Integrated IO-Link interface
  • Two designs: housing with fixed cable and housing with M9 round connector
  • Absolute measurement with 10 µm resolution
  • Non-contact measuring principle
  • Up to 10 m measuring length (EMAX) or 20 m (EMAL)
  • Additional incremental square wave or sin/cos signals for dynamical movement control available


Typical applications are handling systems, storage and conveying technology, injection moulding machines, linear guides
