Black Zinc Nickel Plating
The fully qualified, ‘Z class’ is an aluminium shell with RoHS compliant Black Zinc Nickel plating. This plating is free of Cadmium, hexavalent Chromium, Lead, and any other substances identified as hazardous by the EU, and it has now been adopted as a standard across the globe. Z class meets or exceeds all the same qualification requirements as W class (aluminium shell with olive drab cadmium over nickel plating) as per MIL-DTL-38999. This includes corrosion resistance at 500-hour salt spray rating, durability at 500 mating cycles, EMI shielding effectiveness, and shell to shell conductivity at 2.5 millivolts maximum potential voltage drop, to name a few.
