Incremental optical scale with stainless steel grid, 0.1-10 μm / from 70 mm to 30 m length for press brakes

GVS 202 S

• Self-aligning incremental optical scales, with stainless steel grid
• Optical incremental scale with stainless steel measuring support. High mechanical strength and thermal expansion according to the application, for constant accuracy at any temperature.
• Especially suitable for applications on synchronized press brakes.
• Transducer guided by a self-aligning and self-cleaning sliding carriage with spring system.
• Non-contact read head. No friction: high durability and tolerance to pollution.
• Measuring length up to 30,000 mm, in modular design.
  Resolution up to 0.1 μm.
• Accuracy class ± 2.5 μm in the standard version and ± 1 μm in the high accuracy version. Metrological certificate is supplied with each scale.
• Selectable reference indices every 10 mm over the entire gauge length, with zero magneto-set device.
• The adjustable cable outlet and the selectable zero references make the scale SYMMETRIC and applicable to both columns of the press brake.
• Safety limit switch, positionable at both ends.
• Sealing lips to protect the grille, made of oil- and wear-resistant special elastomer. Self-locking special profile.
• Various application possibilities with double effect connection 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.
