Dual-track linear scale for AP encoders. It contains a Nonius-pattern with absolute stroke 19.2 mm, consisting of track 1 with 16 periods of 1.2 mm and track 2 with 15 periods of 1.28 mm.

The scale consists of a PCB with copper patterns on the front side and with a plain copper surface on the backside. The backside copper layer acts as a screen against metallic structures behind the scale. The scale can thus be mounted on a metallic or non-metallic surface.

The scale can be aligned against a metal edge, the edge height must be less than 0.2 mm.
