Preferred method of assembling a linear scale

Preferred method of assembling a linear scale Synopsis: A linear scale is used to provide feedback on the movement of any axis on a machine. The linear scale has two parts, namely a) Scale, which consists of a metal plate or glass with bars in it, locked in a channel often extruded aluminum. b) scanner, which generates electrical signals when there is a displacement between the scale and scanner. The scanner is composed of signal processing electronics, which conditions the pulses generated for further processing by a CNC or other control and display electronics. In general, the scanner has all the electrical connections and no connection with the scale. Two ways to fix a scale of a slide: Each time a staircase / scanner is fixed linear combination of a slide, one of which is connected to a movable part, and the other at the base of the stationary slide.
