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.
Linear scale applications.
1、All kinds of measuring machines and instruments of linear position detection measurement: spring testing machine, three-axis machine, projector, microscope
2、Digital readout system for all kinds of machine tools: lathe, milling machine, grinder, boring machine, EDM, drilling machine, etc.
3、All kinds of CNC machine tools: CNC milling machine, machining center, CNC grinding machine, etc.
4、with PLC is used for linear position detection measurement of all kinds of automatic equipment.

linear scale 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 136mm; the scales overall length is “L” plus 154mm.
For example, your lathe machine table travel is 900mm, so you need a linear scale in 900mm travel length, the center hole distance is 1036mm, the overall length is 1054mm.
