Project Description
An optical linear position detection sensor (linear scale for short)
is a measurement feedback device that uses the optical principle of the grating to work. The linear scale is often used in closed-loop servo systems of CNC machines for linear position detection measurement. Its measurement output is a digital pulse signal, with a large detection range, high detection accuracy, and fast response time.

WTA(T) linear scale installing dimension 1
Our scale’s travel length is “L” in the above image, the effective travel length is “L” plus 30mm; the center installing holes distance is “L” plus 132mm; the scales overall length is “L” plus 149mm.
For example, you need scale in 150mm travel length, the center hole distance is 282mm, the overall length is 299mm.
Linear scale applications.
