Amphenol Aerospace Launches AP-93 Plating, a 1,000 Hour Alt-to-Cad

Amphenol Aerospace announces a new, durable REACH/RoHS compliant plating for aluminum connectors, called AP-93, which outperforms Cadmium and exceeds 1000 hour salt spray requirements. AP-93 is available under the Amphenol D38999 Series III service class designator “DS”.  It is a conductive finish which meets or exceeds the D38999 Cadmium requirements making it an excellent choice for harsh environments.

Military, commercial, and industrial markets continue to move away from Cadmium due to known toxic carcinogens.  The new AP-93 plating finish complies with all customer requirements tied to these specifications. Amphenol is also using European Union Directive 2002/95/EC RoHS as a guide to qualification for all military, commercial, and industrial specifications requiring the reduction or elimination of these restricted materials.

AP-93 is intermateable with Cadmium, making it a drop-in replacement for applications where Cadmium has been a preferred choice. Applications include numerous components of land, sea, air, and weapons systems, as well as space systems, as it provides sacrificial corrosion protection and excellent lubricity for threaded applications.

AP-93 exceeds Olive-Drab Cadmium plating (Class W) by meeting 1000 hours of dynamic salt spray, 500 mating cycles, and meets the millivolt drop shell-to-shell conductivity of nickel (Class F). AP-93 also meets a 200°C temperature rating, is compatible with other platings, and is available on all D38999-style Series III connectors. For specific applications please contact Amphenol Aerospace.
