MTM-1 Magnetic Measuring System for Piston Rod Profiles

Magnetic Measuring System for Piston Rod Profiles

  • measuring system with one track coded piston rod and sensor
  • for length and position detection of hydraulic cylinders
  • incremental design with two resolutions
  • non-contact, completely non-wearing magnetic measuring principle
  • extremely robust, unaffected by dirt
  • very robust when exposed to shocks and vibrations
  • supply 10 … 30 VDC or 5 VDC possible
  • output level HTL or TTL
