Even When You Lose Power, You Can Count On It

The RSM2800 Magnetic Encoder counts turns, measures angles down to the last degree, and remembers shaft positions without power

Don’t try this with other encoders: imagine your machine with the RSM2800 inside both lose power and are still turning without power; when power is restored, the RSM2800 reports the correct position including the counts that occurred with no power!

RSM2800 magnetic encoders provide the level of reliability and accuracy sought in demanding applications like:

  • Robotics
  • Material Handling
  • Forklifts
  • Overhead Doors
  • Agricultural Machines
  • Cable Extension Transducers
  • Medical Equipment

The RSM2800 is based on Novotechnik’s patented non-contact multi-turn for absolute

5,760° (16 turns) measurement. This new wear-free technology combines advanced capabilities with mechanical simplicity in a very compact and sturdy housing to provide for longer life and lower cost than optical encoders.

RSM2800 Specifications:

  • Absolute multi-turn
  • Up to 16 turns
  • Up to 0.1° resolution
  • Up to 0.1%
  • independent linearity
  • Outputs: 0.1 to 10V or 4 to 20 mA or 0.25 to 4.75V
  • Housing OD=30 mmn
  • IP rating options:IP54 or IP67
  • No gears, no optics, no batteries


New novoturn™ technology by Novotechnik provides engineers with the following unique benefits

▶ No gears, non-contact sensing means long life

▶ Small size for easy integration

▶ Works during power loss for over five years

▶ Maintains accuracy during power loss

▶ Continues to work upon power restoration

▶ Combined counting and position sensing in one part provides accuracy and flexibility

▶ High accuracy with no optics means lower cost

▶ Proven technology extrapolated from hard disk drive technology
