GVS 608

Absolute optical scale for CNC machine tools

Absolute optical scale with glass measuring support, particularly suitable for CNC machine tools.
Serial interface SSI-BiSS C (unidirectional), with or without 1 Vpp analog signal, Siemens DRIVE-CLiQ and FANUC α-αi.
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 720 mm).
Profibus-DP, Profinet, CANopen, DeviceNet and ModBus protocols, through conversion gateways.
Non-extendible sealing lips, along the sliding side of the reader head, fixed at the lateral ends.
Innovative device inside the scale for the disposal of liquids coming from inefficient filtering systems.
The special sealing lips and the device for the liquids disposal provide an excellent protection of the grating
from refrigerant liquids often used during machining.
Metrological certificate provided with each scale.
Linear thermal expansion coefficient λ = 8 x 10^-6 °C^-1.
High accuracy and stability of signals even in case of high speed, strong accelerations and vibrations.
Adjustable connecting cable output.
Connector inside the transducer.
Protected against inversion of power supply polarity and short circuits on output ports.
Small size, to allow installation in narrow spaces.
Interchangeable with the previous model AGS.
Filtering system for pressurization available on request.
