YUANBEN’s magnetic encoder, just one type of non-contact absolute coders, uses a magneto-resistive effect to sense a change in magnetic field, then amplify the change using an amplifying circuit. A single chip then processes and outputs an analog or digital signal in an absolute position. The magnetic encoder is able to sense, measure and give information on its position within a 360° range without the need for a reference point. It can use an SSI synchronous serial communication interface for signal output or utilize CANopen or Profibus-DP for remote transmission.

Due to the magnetoelectric design, YUANBEN’s magnetic encoder features a shock, corrosion and stain resistance, stable performance and simple structure. Multiple mounting methods are available including clamping flange, synchronous flange, synchro-clamping flange, and through-hole. The outer diameter is optional: Φ28, Φ38, Φ48, Φ60.

  • The compact structure and magnetoelectric design allow the magnetic encoder to withstand the toughest industrial environments.
  • High precision, fully digital, no signal interference or zero drift.
  • 3.Baud rate and address code can be set using the dial switch or system software.
  • Resolution (P/R):4096.
  • Wide operating voltage range and low power consumption current.
  • Clamping or synchronous flange conforms to international structure standard.
  • CANopen communication protocol bus output with up to 110 stations
