Encoder Rings

Encoder rings are used in rotary applications where there is a desire to measure rotation speed and angular position. In engines this information is used as input to the engine control system to reduce fuel consumption or optimize performance in demanding situations. These rings can additionally be integrated with the sealing function to limit components and handling.

Key Requirements
  • Strong magnetic signal to accommodate the air gap between encoder and sensor
  • Consistent signal over the entire length of the encoder to enable flexible positioning of the sensor

  • Trostel Provides
  • High performance magnetic encoders created with a proprietary recipe of ferrite loaded polymer
  • Development capability from design through test and measurement
  • Material molded and magnetized to the best pair pole requirement
  • Compact designs to fit in the smallest envelope
  • Manufacturing in North America simplifying logistics and inventory handling
