Single-track linear scale with period length 1.28 mm for ID encoders.
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.
