GVS 219 / Product Support

• Absolutely magnetic length measuring system with pole pitch 2 + 2 mm. Especially suitable for applications on synchronized bending / folding presses.
• Serial interface SSI-BiSS, with or without 1 Vpp analog signal.
• Guided read head with oil and wear resistant elastomer sealing lips with automatic sealing by spring system to protect the magnetic tape.
• Resolution up to 1 μm and reproducibility ± 1 step.
• Accuracy class ± 15 μm.
• SSI protocol and programmable resolutions.
• Profibus-DP, Profinet, CANopen, DeviceNet, Modbus and DRIVE-CLiQ protocols by means of conversion gateways.
• Various application possibilities, with double effect joint or steel wire.
• An adapter ensures interchangeability with the PBS-HR measuring system.
• High stability and quality of signals even at high speed, strong accelerations and vibrations.
• Built-in protection against overvoltage and short circuits, as well as against power supply polarity reversal and short circuits at the output ports.
