The AP5603L absolute encoder kit consists of an encoder and a linear scale. The encoder consists of two integrated circuits in a PCB housing. Each circuit provides an SSI output, optional in Gray or binary code. The linear scale is a PCB with passive copper strips arranged in 2 tracks with an unequal number of periods N1 and N2. The absolute position is calculated by subtracting the two SSI values. The algorithm for this calculation is available from POSIC.

Options like filter-setting and Gray/binary code are user-programmable or can be programmed ex-factory.
