The Molex 50-57-9516 is a 16-circuit, single-row SL crimp housing. It accepts the standard SL crimp terminals and mates with SL pin headers to form a wire-to-board interconnect.
This housing mates with any SL-series single-row pin header of the same 16-circuit count and 2.54 mm pitch. The crimp terminals (sold separately) accept 22–30 AWG wire; the housing's terminal position assurance (TPA) feature locks each terminal in place after insertion.
