Rotary Position Encoder, absolute analog 4-20mA current loop output, 8mm shaft  -  RPE4-8

Please note: This model replaces the retired model RPE3-8. The RPE4-8 has a wider voltage supply range and greater resolution 

Typical Applications:

  • Long run cabling
  • Conveyors
  • Valve angle sensor
  • Materials handling
  • Lever angle sensor
  • Digital potentiometers
  • Mining
  • Robotics encoder
  • Motor speed sensor
  • Industrial actuator position
  • Control position indicator
  • Front panel switch
  • Door position sensing
  • Rotary position sensing
  • CNC Machine tool position
  • Gearbox speed sensor
  • Handwheel or Jogwheel encoders
  • Tool control


  • Hall effect sensor output. Magnetically coupled
  • 360°  continuous rotation. Maximum speed 7500RPM (see below)
  • Voltage supply (VDD) is 12-30V DC
  • 12 bit absolute analog output is 4-20mA increasing for clockwise 360°  - decreasing for counter-clockwise
  • Improved resolution, accuracy and stability
  • Anodised aluminium construction
  • Double ball bearing support of shaft
  • Aluminium shaft 8mm diameter (also available in 6.35mm (1/4") shaft, RPE4-635 , 6.35mm short shaft RPE4-635-S and 6mm shaft RPE4-6
  • Maximum speed with V-ring seal is 3000rpm. Seal can be removed for higher speed max 7500rpm.
  • 3 conductor 22AWG cable with flying lead min. 580mm
  • Rotary encoder
  • RoHS compliant
  • Made in Australia
  • Product code RPE4-8
  • Replaces RPE3-8 but with higher resolution and stability
  • Also available in absolute analog voltage output, and quadrature/index output and PWM output. See RPE-2
