Absolute Encoders icon Absolute Encoders

US Digital designs and manufactures absolute encoders in optical configurations for the highest possible resolution and accuracy and magnetic versions for demanding environments. In either case, absolute encoders report a shaft angle within a single 360-degree shaft rotation without stops or gaps. Unlike incremental (sometimes called relative) encoders, absolute encoders provide true (absolute) shaft position, eliminating the need for a home or zero cycle after a supply voltage power cycle.

Kit Absolute Encoders

Kit-style encoders enable easy assembly onto existing shaft and bearing assemblies. Each US Digital kit encoder is available with a digital output and an optional analog output scalable to application needs.

Shaft Absolute Encoders

Absolute shaft encoders incorporate their own shaft and bearing assembly, which in turn is coupled to the motor shaft with a belt, gear train or coupling. The encoder may then report shaft angles within a single 360-degree shaft rotation without stops or gaps.
