Absolute Encoders


TRD-NA Series


An absolute encoder uses gray code to describe each position, so position data is not lost when power is cycled. When power is cycled using an incremental encoder, any positioning information is lost until “home” position is triggered.
  • Small body with 50mm diameter and 35mm depth
  • Stock and non-stock models range from 5 bit to 10 bit Gray code outputs
  • 8 mm stainless steel solid shaft
  • Accept source voltages from 10 V to 26 VDC
  • 20 KHz maximum response frequency
  • IP65 Rating (splash proof)
  • CW (clockwise) revolution
  • Data Sheet (345kb)
Why use an absolute encoder? When power is cycled when using an incremental encoder, any positioning information is lost until home position is triggered. An absolute encoder uses gray code to describe each position, so position data is not lost when power is cycled.
