Rotary encoder-ED—21
Product Description
The ED-21 series magnetic encoder is designed to replace traditional mechanical potentiometers. This product 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 electromechanical potentiometers with sealed electronics, extended temperature ranges, and virtually unlimited life as there are no mechanical parts to wear out.
