As a light duty feedback sensor the ED-18 magnetic encoder can provide rotation speed, direction or positioning information.  The analog output provides absolute angular position information even when power is cycled on and off. As an HMI device it can be used as a rotary input control for use on instrumentation panels. The ED-18 Series is designed with our modular and flexible construction methods.
