MTM-I Magnetic translational Incremental Encoder Wear-free Position Measurement on Round Bars / Piston Rods

The MTM-I measuring system is based on the magnetic measuring principle and serves for the high-precision incremental adjustment of the piston position on cylinders.

  • Measuring system with single track coded piston rod and sensor
  • For length and position detection in hydraulic cylinder
  • Incremental design with two resolutions
  • Non-contact, completely wear-free magnetic measuring principle
  • Extremely robust, unaffected by dirt
  • High shock and vibration stability
  • Power supply voltage 10 ... 30 VDC or 5 VDC
  • Output level with HTL or TTL
