Features

Velox® connectors feature a robust design, including a gold plating layer 1.27 μm (50 microinches) thick. The contacts are recessed, providing additional protection. These features contribute to a service life of at least 200 mating cycles. Velox® is therefore particularly suitable for high-speed backplane applications with a data throughput of 10 Gbit/s. The connectors’ high durability has already been proven in tests conducted in accordance with the VITA-46 standard.

The VITA46 Specification

The VITA 46 specifications, also known as VPX, describe a new high-speed connector system. Among other things, it supports Gigabit Ethernet, PCI Express, Serial RapidIO, and InfiniBand. The 6U and 3U Eurocard form factors familiar from the VMEbus are supported to ensure maximum compatibility. This also makes hybrid systems possible. The VITA 46 standard was developed by the VITA organization primarily for computer systems that must withstand high loads, such as in military applications.

Four different designs can be combined with each other in a modular fashion. Velox® connectors are highly flexible due to the varying number of contacts. This feature is underscored by the ability to populate the variants individually.

Developer's perspective

"The Velox® connector system was developed by ept specifically for VITA-46 systems, also known as VPX. The Velox® system includes four different connector types that can be linked together in a modular fashion. Customers can select the number of contacts, ordering either fully populated connectors with 72 or 144 contacts or a custom contact configuration. This architecture delivers extensive design flexibility for printed circuit board (PCB) developers. Velox® was engineered specifically for high-performance applications, and its gold plating and fully enclosed contacts within the insulator body ensure exceptional durability.
