HARRISBURG, Pa. TE Connectivity is now providing RoHS (Restriction of Hazardous Substances)-compliant black zinc nickel plating for backshells and connectors to reduce the use of cadmium, per new environmental regulations.

The black zinc nickel plating is MIL-DTL-38999L approved, and offers the same level of electrical performance, environment protection, and temperature ranges as cadmium plating.

“We’re pleased to be able to offer a solution helps our customers reduce cadmium usage and provides enhanced performance over similar products,” says Chris Novak, product manager, Global Aerospace, Defense & Marine, TE Connectivity. “And, because black zinc nickel and cadmium have similar electrical potential, new parts can be easily integrated into existing applications without additional engineering or excessive downtime.”

The black zinc nickel finish is non-magnetic and non-reflective and is ideal for various applications, such as: aerospace, automotive, communications equipment, electric drive vehicles, mass transit, metering equipment, next-gen harsh-environment vehicles, and power generation, among others.

The new black zinc nickel plating option is available on TE’s DEUTSCH standard MIL-DTL-38999 Series III or DTS High Current connectors and Raychem standard backshells and accessories. The Raychem bandstrap backshells are also approved to the AS85049 specification for black zinc nickel with 1000-hour salt spray resistance testing.
