The linear scale read head is part of the truck assembly; there is one read-head per axis.
The previous diagram illustrates the position of the Schneeberger truck/read-head assembly as they appear on the machine’s axes (Numbers X,Y and Z).
Also note the positon of the read-head cable junctions (Letters X1, Y1 and Z1).
Both of these areas will need to be located in order to correctly dissassemble and disconnect the scale.
As mentioned the diagram only shows the positions of one manufacturer’s linear scale truck assembly and associated electrical connection area.
Other manufacturer’s scales are installed in a similar manner, but the read-head may be in a different location.
