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.
