 MECHANICAL AND ELECTRICAL CHARACTERISTICS                                                                   

MECHANICAL

·    PROFILE made of anodized aluminium. Dimensions 23x18 mm.

·    RAIL for the sliding of the intermediate fixing blocks, positionable along the entire measuring length, necessary for the intermediate fixing of scales with measuring length over 700 mm.

·    Elastic COUPLING for misalignment compensation and

self-correction of mechanical hysteresis. Backlash error <0.2 μm.

·    SEALING LIPS for the protection of the grating, made of special elastomer resistant to oil and wearing.

·    READER HEAD, consisting of tie rod and reading block, with fully-protected place for electronic boards.

·    READING BLOCK sliding through ball bearings.

·    Die-cast TIE ROD, with nickel surface treatment.

·    Stainless steel GRATING dimensions 15x0.203 mm in a single piece. The support maintains the grating in its position leaving it free to expand.

·    Elastomeric GASKETS which allow to reproduce the full protection in mechanical joints (in case of disassembling).

·    Full possibility to disassemble and reassemble it.

·    Possibility of direct service.

 

ELECTRICAL

·    Reading device with high-efficiency light emitter and single-field photodiode.

·    A and B output signals with phase displacement of 90° (electrical).

·    Reference indexes at constant step, in central position or in different positions at request.

·    CABLE:

-  8-wires armored cable Æ = 6.1 mm.

-  Conductors section: power supply 0.35 mm2; signals 0.14 mm2. GVS 300 scale is normally supplied with armored cable.

PVC, PUR, ultraflex or tuboflex cables available on request.

PUR cable is suitable for continuous movements, respecting a minimum bending radius of 80 mm.
