Applications

The D38999/20KA35SN is a Series III wall mount receptacle in shell size 9 (A) carrying six size-22D socket contacts on the A35 insert arrangement. The K class shell is passivated stainless steel rather than cadmium-plated aluminium: it does not embrittle at high temperature, carries the firewall rating required for engine and APU-adjacent bulkheads, and removes the cadmium corrosion and REACH considerations that apply to olive drab plated parts. It is the usual specification where the connector must survive a designated fire zone or mount to a stainless structure without galvanic mismatch. The four-hole square flange takes standard Series III panel cut-outs and mates with any D38999/26 plug of the same shell size and arrangement.
