1.80mm-Pitch Sealed Receptacle for Dense Automotive Harnesses
The Molex Mini50 0348948008 is a 16-circuit receptacle in the Mini50 34894 series, built for sealed, space-constrained wire-to-wire interconnects in automotive and industrial applications. It uses a 1.80mm pitch — roughly half the spacing of a standard 0.100-inch header — which lets you pack more circuits into the same connector footprint. That is the difference between a connector that stays sealed at 125°C and one that leaks after a few thermal shocks. The free-hanging (in-line) mount and crimp termination mean it terminates on a wire harness, not a PCB.
Sealed Construction and CPA — What the Features Mean
The sealed housing keeps moisture and contaminants out of the terminal cavity. In an engine bay or transmission environment, that is what prevents fretting corrosion on the crimp joint. The CPA is a secondary lock that engages after the primary latch — it prevents partial mate that would break the seal interface. If you are specifying for a USCAR application, both CPA and TPA (terminal position assurance, handled by the crimp terminal) are expected. The 1.80mm pitch and 0.081" row spacing are tight enough that the CPA is a practical necessity — without it, a partially seated connector in a dense harness bundle is hard to detect by feel. The 2-row, 16-position layout gives 8 circuits per row. The gray color is standard for this variant — color coding across the Mini50 family helps prevent mis-mating on the line. The bulk packaging is typical for harness-build quantities; no tape-and-reel for this free-hanging housing.
