Black zinc connectors replace cadmium for ROHS compliance

23rd September 2014

TE Connectivity (TE) has launched a new range of RoHS-compliant black zinc nickel plating for connectors and backshells, writes Nick Flaherty. 

The new coating is TE’s response to new environmental regulations that seek to reduce the use of cadmium.

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

“We’re pleased to be able to offer a solution helps our customers reduce cadmium usage and provides enhanced performance over similar products,” said Chris Novak, product manager, Global Aerospace, Defense & Marine at 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.”

TE’s Raychem standard backshells can be supplied with the new RoHS compliant black zinc nickel plating and the bandstrap backshells are approved to the AS85049 specification for black zinc nickel with 1000-hour salt spray resistance testing.

Black zinc nickel finish is non-magnetic and non-reflective and ideal for a variety of applications including next-generation harsh-environment vehicles, electric drive vehicles, aerospace, mass transit, automotive, communications equipment, power generation and metering equipment.
