Application

D38999/46WJ61SA is the /46 EMI grounding plug at shell size 25 (letter J) on the 25-61 insert: 61 size-20 contacts, socket side, keyed A. Socket contacts on a plug are the less common configuration and matter when the harness side must be the protected half of the pair — the pins then sit in the fixed receptacle where they cannot be bent during handling. The /46 coupling ring adds spring grounding fingers so the shells bond before the contact field engages, and key A offsets the insert clocking from normal so a key-N receptacle will not mate. Finish W is cadmium olive drab over conductive underplate.
