Absolute optical scales with stainless steel grid / Measuring length: 70 mm to 6'000 mm / Press brakes and automation / ± 1 μm

GVS 206 S

• Optical scale with stainless steel measuring rest and direct reading of the absolute position.
• High mechanical strength and thermal expansion according to the application, for constant accuracy at any temperature.
• Especially suitable for applications on synchronized press brakes.
• SSI-BiSS C high-speed serial interface (unidirectional).
• Option: Line Driver digital signal.
• Transducer guided by a self-aligning and self-cleaning carriage with spring system.
• Non-contact read head. No friction: high durability and tolerance to pollution.
• Measuring length up to 6,000 mm, in modular design.
• Resolutions down to 0.1 μm.
• Degree of accuracy ± 2.5 μm in the standard version and ± 1 μm in the high-precision version. Metrological certificate is supplied with each scale.
• Profibus-DP, Profinet, CANopen, DeviceNet, ModBus and DRIVE-CLiQ protocols via conversion gateways.
• Sealing lips to protect the grille, made of oil- and wear-resistant special elastomer.
• Self-locking special profile.
• Wide range of applications, with double effect joint or steel wire.
• Interchangeable with the line GVS 2xx and with the previous model PBS-HR.
• High accuracy and stability of signals even at high speeds, strong accelerations and vibrations.
• Molded M12 connector (IP 67) or other models on request.
• Protected against reverse polarity of the supply voltage and short circuits at the outputs.
