Gurley offers three technologies for rotary encoders: incremental, true absolute and our patented Virtual AbsoluteTM brand.

Linear Encoders are generally available in two types, absolute and incremental, and are defined by their position signals. Absolute linear encoders create a unique position signal that is available anywhere along travel with the exact position being read after power cycling. Incremental encoders do not generate a unique signal and is zeroed after power-down. They rely on another switch or encoder for initial reference.
