GVS 219 Absolute Magnetic Grid Ruler

General characteristics:

▪ Directly read the absolute position of the magnetic grid ruler. Especially suitable for synchronous bending machines

▪ high-speed serial interface

▪ The reading head is guided by a self aligning and self-cleaning slider with a spring system

▪ Resolution up to 0.1 μ M

▪ Reading without contact

▪ Adjustable cable output position

▪ Symmetrical mechanical installation.

▪ The use of universal joint rods or steel wires brings various possibilities for application installation.

▪ Option: 1 Vpp analog signal.

Mechanical and electrical characteristics

Mechanics:

▪ Durable and weighted anodized aluminum profiles with a cross-sectional size of 55 * 28mm

▪ Elastic couplings can compensate for misalignment and automatically correct mechanical hysteresis.

▪ Oil resistant and wear-resistant sealing lips made of special rubber are used to protect magnetic tapes. Special self blocking profile

▪ The carriage is guided by ball bearings with Gothic arch shaped contours and slides on guide rails that have undergone thermal expansion and grinding processing, ensuring the accuracy of the system and preventing wear.

▪ The surface is treated with nickel electroplating for die-casting pull rods.

▪ Absolute magnetic tape placed inside the ruler casing

▪ The elastic gasket allows for comprehensive protection of the mechanical joint when disassembled.

▪ The use of universal joint rods or steel wires brings various possibilities for application installation. The GB-PB adapter ensures compatibility with PBS HR rulers.

▪ Configure pressurization as required.

▪ The possibility of complete disassembly and reassembly of the ruler

▪ The possibility of direct repair

Electrical characteristics:
