Combining the benefits of field proven MIL-DTL-38999 Series III circular connectors with hyperbolic contacts that extend the boundaries of high power connector technology, the Rhino 38999 Series connector from Amphenol is designed not only to meet the latest military and industrial specifications but will also meet stringent safety requirements
As one of the foremost manufacturers of both connectors and interconnect systems specifically for applications within military, aerospace and industrial markets, Amphenol has recognised a distinct trend towards increased power and voltage requirements within such applications as military and electric drive vehicles, aircraft and intelligence bases stations.
The use of RADSOK contacts creates an electrical interface that exceeds typical interconnect requirements via a hyperbolic socket contact construction which distributes normal forces over a high percentage of the mating surface to ensure a smooth and even engagement force with exceptionally high performance under vibration. The large surface area of the socket contact also results in a very low contact resistance enabling much higher current ratings compared to other power contact designs.
High reliability applications including vehicular, aerospace, industrial, automation, mining, offshore and other harsh environments can all be addressed using the Rhino 38999 Series. The Series provides IP2X finger protection on both plugs and receptacles. Flange Mount, Jam Nut or Inline connection is offered with high reliability, low contact resistance RADSOK contacts which feature durability up to 500 mating cycles.
Available in a variety of shell materials including aluminium, stainless steel and aluminium bronze, the connectors can be provided in standard 38999 Series III shells or the new Bulldog breakaway connectors style. Overmoulded cable harnesses are also available.
Offering current ratings of 100-750A and operational voltage ratings of 630V, the connectors also provide 360° screening. Environmental features include a temperature range of between -45°C to +125°C, IP68 sealing and surface finishes comprising of cadmium, zinc cobalt and newly available Black Zinc Nickel RoHS compliant plating.
Amphenol announced the availability of a new RoHS compliant plating alternative to cadmium. Black zinc nickel plating is now available on a wide variety of connectors and accessories including proprietary MIL-DTL-38999 and MIL-C-26482. This conductive and non-reflective black finish is approved for 500hrs salt spray endurance and is fast becoming the new defence industry standard. Although there is an exemption for the use of cadmium in military applications, for several years, manufacturers have reduced its use but have accepted reduced performance as a consequence.
In response to industry demands, Amphenol has designed and installed a new processing line at their Whitstable, UK facility to enable plating with black zinc nickel; a conductive and environmentally sound surface treatment. The salt spray performance of black zinc nickel plating makes it an excellent choice for applications in a highly challenging environment.
Electrically, the conductivity of black zinc nickel plating ensures shell-to-shell continuity of less than 2.5mO, and less than 5mO after 500hrs salt spray chamber time. This superior electrical performance ensures that high levels of EMC screening can be maintained within sensitive systems in demanding situations.
Amphenol has tested its black zinc nickel plating to show no significant galvanic reaction when mated to alternatively plated legacy product such as cadmium, zinc cobalt or Electroless nickel.
