SV Microwave offers VITA Backplane Modules SV Microwave offers VITA Backplane Modules aligned to the SOSA Technical Standard. Amphenol SV Microwave is an active member of the SOSA standard’s committee and spearheaded the effort to include RF industry-recognized interfaces like SMPM and SMPS as open standards.


The CMM from NicomaticThe CMM from Nicomatic is a modular rectangular connection system with a 2 mm pitch, allowing the creation of more than 20 million standard configurations (HF, HP, LF contacts, from 1 to 3 rows and up to 120 contacts). CMM features flexible architecture for board-to-board, board-to-wire, and wire-to-wire. It achieves significant space savings (up to -40% in area and -60% in volume) compared to other rectangular connectors with a weight gain of -20% to -50% compared to solutions with the same functionalities. Robustness of PPS means a low degassing rate, resistance to radiation and solvents, and no moisture absorption. CMM offers resistance to temperatures between -60 °C and + 260 °C (temperature cycle) and is ideal for applications with shock and vibration, thanks to its high-performance mechanical fixing system. MIL-DTL-55302F and BS-9525-F0033.

TE Connectivity’s MULTIGIG RT 3 and MULTIGIG RT 2-S connectors from TTITE Connectivity’s MULTIGIG RT 3 and MULTIGIG RT 2-S connectors from TTI are next-generation lightweight, rugged, high-speed, backplane connectors that meet the interface dimensions for VITA 46 VPX connectors. The connectors are backward compatible with legacy MULTIGIG RT products and offer the same reliable interface. The MULTIGIG RT 3 connectors support speeds up to +25 Gb/s and offer a ruggedized design, which makes them ideally suited to withstand many extreme military and space environments. The quad-redundant contacts meet rigorous VITA standards for reliable performance under intense vibrations. A modular design enables numerous configurations by interchanging the higher-speed MULTIGIG RT 3 connectors with the legacy MULTIGIG RT 2 and MULTIGIG RT 2-R connectors. MULTIGIG RT 3 and MULTIGIG RT 2-S applications include aviation, military & defense, and space.

Phoenix Contact’s HEAVYCONPhoenix Contact’s HEAVYCON has thousands of components that can be used to create over 70 million different product combinations. Many common application requirements can be satisfied with a select set of those components. The unique snap-in modular frame locks in each modular insert with its own set of locking springs. This assembly feature can reduce the modular insert assembly time by up to 400%. The modular snap-in frames are fully compatible with most other suppliers’ inserts and frames.

Weidmüller’s RockStar heavy-duty connectors Weidmüller’s RockStar heavy-duty connectors are oriented toward the future with many patented innovations. The RockStar product line defines new standards with the comprehensive depth and breadth of its features. What other suppliers offer only as a custom configuration, Weidmüller supplies in its standard product line. As a result, selecting the proper connector
is now easier than ever, saving time and money, and optimizing workflow. The connector housings are made of die-cast aluminum and offer excellent protection against dirt, moisture, and mechanical stress. Modular connectors make it possible to integrate signals, power supply and data connections into a single connector.

Velox from ept Velox from ept is a modular backplane connector system for high-speed applications.
