High-power connectors

15 August 2018 Interconnection

Amphenol has a broad range of high-power connectors to offer the military and industrial market. Combining the benefits of field proven MIL- DTL-38999 Series III circular connectors with hyperbolic RADSOK contacts, the 1000 A Rhino 38999 series connector is designed to meet the latest military, industrial and safety requirements. Alongside Rhino 38999, Amphenol also has a complementary range of higher-power MIL-DTL-38999 connectors.

In the single-pole Rhino 38999 connectors, the use of RADSOK contacts creates an electrical interface that exceeds typical interconnect requirements via a hyperbolic socket contact construction, which delivers very low contact resistance and performs exceptionally well under high vibration. Rhino 38999 connectors offer current ratings of 85 A up to 1000 A and operational voltage ratings of up to 1200 V d.c., with 360 degree EMC/RFI screening.

Environmental features include a temperature range of between -55°C to +150°C, IP68 sealing and 500 hours salt spray tolerance. Amphenol is also able to use the same product technology in multi-pole options, both rectangular and circular, with the additional benefit of safety inter-lock contacts to enable hot-swapping.

Alongside the higher-current Rhino 38999 connectors, Amphenol also manufactures an extended range of standard MIL-DTL-38999 series III specification multi-pole connectors with larger contact sizes to carry current up to 100 A. These connectors are available with crimp contacts and also tapped-hole contacts to suit busbar termination. Example insert arrangements include the popular 21-42 and 21 - 75 styles.

Both power connector series are available in a variety of shell materials including aluminium, stainless steel and aluminium bronze, and can be provided with RoHS-compliant black zinc nickel plating.

Amphenol’s broad offering of power products is suitable for high-reliability applications including harsh environments as well as hybrid and electric drive vehicles, military aircraft, naval systems, C4I base stations, power distribution modules, communication towers, satellite communications, mass transit, automation and mining.

The connectors can also be supplied as over-moulded cable harnesses providing a complete interconnect solution.
