The Ringdale 12-bit absolute encoder is housed in a rugged anodized aluminum enclosure. A 10mm stainless steel shaft turns on dual sealed ball bearings. Electrical connection is through a recessed, sealing connector mounted in the end of the encoder.

The encoder transmits its shaft position as a 12-bit value through an RS-422 interface. The data output is free-running and does not require a clock signal.

In a radar position application, the Ringdale 12-bit absolute encoder is rigidly mounted adjacent to the 1-1/2 radar shaft. A timing belt transfers rotation from a split pulley assembly on the radar shaft to an equally sized pulley on the encoder shaft.
