Unless operated on, the catalogs still use these familiar terms , but P and S is preferred for contacts and P and J or Rcpt for shells. When using schematics, onboard is J1..... Floating connectors are Plugs , P1,... Board to board J...
plug to plug... P and contacts still called M or F type . Regardless of what military say. It's easy to get confused until you laff about it.
And we still call PCB's as such inspite of toxic chemical of same instead of the military, printed wiring boards PWB's, because very few electronics folks work with transformers still cooling and insulating with PCB's now obsolete.
