14-Circuit SL Crimp Housing — Non-Polarized, Single Row
The Molex 50-57-9014 is a 14-circuit, single-row SL series crimp housing. The 'NP' in the description — non-polarized — means the housing lacks the polarizing pegs found on some SL housings, so it fits headers without a matching keyway.
The housing accepts standard SL crimp terminals (sold separately) for 22-30 AWG wire. The single-row layout and non-polarized design mean the housing can be installed in either orientation on the header, which simplifies harness assembly but means the installer must verify the circuit-to-pin mapping. The primary latch on the housing locks audibly when mated, giving a positive retention check without a secondary lock.
