Linear Glass Scales
A glass scale is installed in the linear scale guaranteeing high accuracy. There are four types of linear scale: Satandard, Slim, Ultra-slim and long scale type.
Style Type Range
Standard JSM 50~3000 (mm)
Slim JSS 50~1000 (mm)
Ultra Slim JSN 50~450 (mm)
For long scale JSH 1000mm ~

By the relative moving of MAIN scale and INDEX scale, light signal is changed to Electric signal.
After that, it is made to high divisional signals via the Electric circuit
