MECHANICAL AND ELECTRICAL CHARACTERISTICS   

MECHANICAL

·  Rugged and heavy PROFILE, made of anodized aluminium. Dimensions 55x28 mm.

·  Elastic COUPLING for misalignment compensation and self-correction of mechanical hysteresis.

·  SEALING LIPS for the protection of the magnetic band, made of special elastomer resistant to oil and wearing. Special self-blocking profile.

·  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 MAGNETIC BAND 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

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

·  Serial protocol SSI - BiSS C (unidirectional).

·  Reading through positioning sensor based on magneto resistance, with AMR effect (Magnetic Anisotropy).

·  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 + 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.
