Magnetic encoder ED-18 Series

Image ED-18

The ED-18 Series Magnetic Encoder can be used as either a rotational feedback sensor or as a human machine interface (HMI) device.

As a light duty feedback sensor it 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. We can customize housings, shafts and terminations to meet your exact specifications with little or no tooling costs.
