Absolute linear encoder GVS 508

opticalSSIIP64

Absolute optical scale with glass measuring support. Resolutions up to 10 nm. Accuracy grade ± 5 μm in the standard version and ± 3 μm in the high accuracy version (± 2 μm for measuring lengths up to 670 mm). High resistance to environmental dirt. Central fixed expansion point (FEP). On request positioned on the right (RT) or on the left (LT), for a linear expansion consistent with the type of application. Metrological certificate provided with each scale. Linear thermal expansion coefficient λ = 8 x 10-6 °C-1. Direct reading of absolute measure. Connector on the transducer. Protected against inversion of power supply polarity and short circuits on output ports. Small size, to allow installation in narrow spaces. Pressurization from both sides of the scale or from the transducer. Brochure
