Incremental or absolute scale, based on optical or magnetic technology, suitable for applications on synchronized press brakes
The Givi press brake scale has a reader head guided by a self-aligned and self-cleaning sliding carriage with spring system
Resolution up to 0,1 μm. Accuracy grade up to ± 1 μm
Linear thermal expansion coefficient specific to the optical grating or the magnetic band used
Reference indexes at coded distance or selectable every 10 mm along the entire measuring length, with Zero Magneto Set device
The Givi press brake scale has safety limit switches, that can be re-positioned at both ends
The adjustable cable output and the selectable zero references make the Givi press brake scale symmetric and applicable to both columns of the press brake
MECHANICAL CHARACTERISTICS
Rugged and heavy profile made of anodized aluminum. The Givi press brake scale dimensions are 55 x 28 mm
Elastic coupling for misalignment compensation and self-correction of mechanical hysteresis. Extremely low backlash error (< 0,2 μm)
The Givi press brake scale has sealing lips for the protection of the grating, made of special elastomer resistant to oil and wearing
Carriage guided by ball bearings with gothic arch profile sliding on tempered and grinded guides, to guarantee the system accuracy and the absence of wearing
Reading block sliding through ball bearings (optical version) or without contact (magnetic version)
Elastomeric gaskets on the Givi press brake scale allows to reproduce the full protection in mechanical joints (in case of disassembling)
Various possibilities of application, with double-effect joint or steel wire. An adapter guarantees the compatibility with PBS-HR scale
Measuring and control systems
ELECTRICAL CHARACTERISTICS
Reading device with a single infra-red light emitter and receiving photodiodes. The Givi press brake scale has a feedback circuit for a higher stability of output signals
A, B and Z Push-Pull or Line Driver output signals, with phase displacement of 90° ± 5° electrical
8-wires shielded cable. The Givi press brake scale has conductors sections suitable for long cables. PUR external sheath, self-extinguishing and resistant to oil, crushing and torsions. Suitable for continuous movements
Protection against inversion of power supply polarity and short circuits on output ports. The Givi press brake scale has the availability of different power supplies
