Overview

The ED-21 magnetic encoder is offered with a ball bearing supported shaft. Two standard output options are available: 0.5 VDC to 4.5 VDC or 4 mA to 20 mA. The magnetic technology used in the ED-21 offers advantages over conventional electro-mechanical potentiometers with sealed electronics, extended temperature ranges, and virtually unlimited life as there are no mechanical parts to wear out.

BENEFITS

  • Analog voltage or current output
  • Low profile
  • IP52 sealing
  • Ball bearing 
  • Magnetic sensing technology
  • Encapsulated electronics/sealed
  • Harsh environment compatibility
