Amphenol Ltd is pleased to offer a new RoHS compliant plating alternative to Cadmium. Black Zinc Nickel plating is now available on a wide variety of connectors and accessories including Mil-DTL-38999 and proprietary
Mil-C-26482 ranges of connectors. This conductive and nonreflective black finish is approved for 500hrs salt spray endurance and is fast becoming the new Defence Industry standard. 

Until recently, Cadmium plating has been the industry preference for Aeronautical and Defence applications, widely selected for its environmental and electrical performance.  However, the latest ecological and sustainability regulations now seek to reduce or eliminate the use of Cadmium.  In response to market demands, Amphenol Ltd has designed and installed a new processing line at its 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 highly demanding environments.

 Electrically, the conductivity of Black Zinc Nickel plating ensures shell-to-shell continuity of less than 2.5mΩ and less than 5mΩ after 500hrs salt spray chamber time. This superior electrical performance ensures high levels of EMC screening can be maintained within sensitive systems in demanding situations.

Amphenol Ltd 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.

Plating Facility

Amphenol Ltd has been plating connectors and interconnect components at its manufacturing site in Whitstable, Kent for over 40 years.  Expanding on its vast experience and knowledge of materials and plating finishes, Amphenol Ltd has recently invested in a new Black Zinc Nickel plating line, set up in accordance with best practices meeting environmental legislation and providing superior quality plated parts.
