The ID4501L incremental encoder kit consists of an encoder and a linear scale. The encoder is an integrated circuit in a PCB housing. It provides incremental A and B output signals in quadrature. The linear scale is a PCB with passive copper strips.

The resolution and the maximum speed of the encoder are user-programmable or can be programmed ex-factory.
