Rotary Encoders

RPE-PV Programmable Rotary Encoder. Newall’s RPE-PV features a dynamic encoder resolution capability that allows users to easily program the encoder resolution to any value between 1 and 10,000 counts per revolution. Users can program and reprogram the encoder’s resolution on site as needed. Using the optional programming cable, connect the encoder to a computer via the USB port. Simply enter the new resolution and click ‘Program’. A new resolution is now programmed. It’s just that simple.


  • Benefits:
  • Simple to program
  • Installs just like a standard encoder
  • Instant positive indication of the programmed value
  • High speed operation due to high base count
  • Wide range of possible counts per revolution CPR - 1 to 10,000
  • Automatic index pulse positioning
  • Easily change CPR for prototyping situations and machine set-ups
  • Reduce stock of different CRP encoders for maintenance (keep just one type in stock and program it as needed)
