OPTICAL SCALES

GMS – Incremental modular optical scale

Modular optical scale with stainless steel grating, particularly suitable for long strokes (measuring length up to 30,040 mm).
Rugged and heavy profile, in anodized aluminium.
Coupling gaskets between the modules for a better fit of mechanical parts (in case of disassembly and reassembly).
Resolutions up to 0.1 μm.
Accuracy grade ± 10 μm.
Linear thermal expansion coefficient λ = 10.6 x 10-6 °C-1 suitable for the application.
Reference indexes at coded distance, or at constant step (50 mm) or selectable.
Sine-wave or TTL signal output.
Protected against inversion of power supply polarity and short circuits on output ports.
