ABSOLUTE OPTICAL SCALE GVS 204 

ĐẶC ĐIỂM CHUNG

MECHANICAL

·  Rugged and heavy PROFILE, made of anodized aluminium. Dimensions 55x28 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. Special self-blocking profile.

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

·  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.

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

·  Absolute GLASS GRATING placed in the scale housing.

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

·  Adjustable CABLE output.

·  Various possibilities of application, with double-effect joint or steel wire. GV-PB adapter guarantees the compatibility with scale mod. PBS-HR.

·   Full possibility to disassemble and reassemble the scale.

·   Possibility of direct service.

 

ELECTRICAL

·  Reading device with an infra-red light emitter and receiving photodiodes.

·  Option: A and B (analog 1 Vpp or digital Line Driver) output signals with phase displacement of 90° (electrical).

·  Serial protocol SSI - BiSS C (unidirectional).

·  CABLE:

- Shielded twisted pair for digital signals (SSI - BiSS).

- The cable is suitable for continuous movements.

SERIAL OUTPUT VERSION

- 6-wire shielded cable Æ = 7 mm, PVC external sheath, with low friction coefficient, oil resistant.

- Conductors section: power supply 0.25 mm2; signals 0.25 mm2.

The cable’s bending radius should not be lower than 70 mm.

ANALOG or DIGITAL + SERIAL OUTPUT VERSION

- 10-wire shielded cable Æ = 7.1 mm, PUR external sheath.

- Conductors section: power supply 0.35 mm2; signals 0.10 mm2.

The cable’s bending radius should not be lower than 80 mm.
