Incremental glass scale / from 70 mm to 3'240 mm / press brakes / ± 1 μm accuracy

GVS 200

• Optical incremental length measuring system with glass scale. Especially suitable for applications on synchronized press brakes.
• Reading head through a self-aligned guide and self-cleaning carriage with spring system.
• Resolution up to 0.1 μm.
• Accuracy class ± 2.5 μm in the standard version and ± 1 μm in the high-precision version.
• The metrological certificate is provided with each length measuring system.
• Reference indices at coded distance or selectable per 10 mm over the entire measuring length, with the zero magneto set device.
• The adjustable cable exit and the selectable zero references make the measuring system symmetrical and applicable for both columns of the press brake.
• Safety limit switch, positionable at both ends.
• Sealing lips to protect the grille, made of special oil-resistant elastomer.
• Various application possibilities, with double effect joint or steel wire.
• An adapter ensures compatibility with PBS-HR scales.
• High stability and quality of signals even at high speed, strong accelerations and vibrations.
• Form M12 connector (IP 67) or other models on request.
• Protection against polarity inversion of power supply and short circuit on output.
