GVS 200 pull rod grating ruler (automatic alignment)

General characteristics:

▪ The grating ruler with glass grating (grating spacing of 20 μ m) is particularly suitable for synchronous bending machines

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

▪ The resolution reaches 0.1 μ M. The accuracy level can reach ± 1 μ M

▪ Specially set linear thermal expansion coefficient for the grating or magnetic grating strip used

▪ Equipped with a zero setting magnetic block, the reference point setting method can encode distance or set every 10 millimeters along the entire measurement length.

▪ The safety limit switch can be placed at both ends.

▪ Adjustable output cable direction and optional zero reference point enable the ruler to have symmetry and can be used uniformly on both columns of the bending machine.

mechanical properties

▪ 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. Extremely low recoil error (<0.2 μ M)

▪ Oil resistant and wear-resistant sealing lips made of special rubber, used to protect gratings

▪ 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

▪ The reading head block slides through ball bearings (optical version) or non-contact (magnetic version)

▪ The elastic gasket allows for sufficient protection of the mechanical joint during disassembly.

▪ 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.

▪ The possibility of complete disassembly and reassembly of the ruler

▪ The possibility of direct repair

Electrical characteristics:

▪ The reading device is equipped with an infrared emitter and a receiving photodiode. The output signal guaranteed by the feedback circuit has high stability

▪ A. On the B and Z push-pull or line driven output signals, the signal is equivalent to 90 ± 5 degrees

▪ 8-wire shielded cable. The conductor part is suitable for long-distance transmission. PUR outer sheath, self extinguishing, oil resistant, resistant to breakage and torsion. Suitable for continuous movement

▪ Power polarity reversal and output port short circuit protection. The possibility of working with different power sources
