Cable assemblies enhance electrical performance

The EQRD Series of Q Rate coax cable comprises a 50ohm single-ended 34 AWG micro coax ribbon cable system with a choice of 26, 52 or 78 contacts per row and a standard friction lock.

Performance is 4Gbps at 1m.

The EQRP Series of Q Rate Twinax cable comprises a 100ohm differential-pair 30 AWG twinax ribbon cable system available in 18, 36 or 54 pairs.

Performance is almost 10Gbps at 1m.

The 0.8mm (0.0315in) pitch cables mate with Samtec's slim-body Q Rate socket and terminal strips (QRF8/QRM8 Series).

Mated heights of 11.5mm or 14.45mm and overall cable lengths from 95.3mm (3.75in) to 1m (40in) are standard.

Optional screw-downs as well as application-specific sizes, cable lengths, terminations and wire gauges are also available.

Q Rate connectors and cable assemblies use Samtec's Edge Rate contacts.

Edge Rate contacts are designed specifically for excellent electrical performance and durability.

A smooth-milled contact design provides for a low insertion/withdrawal force, allowing 'zippering' during un-mating.

The positioning of the contacts relative to the ground plane results in excellent signal integrity, while the contact design reduces broadside coupling and crosstalk, according to the company.
