Sealed 12-Circuit Receptacle for Harsh-Duty Harnesses
The Molex 1600746003 is a sealed, 12-circuit receptacle from the MX150 160074 series, built for wire-to-wire interconnects in environments where moisture and vibration are daily realities. The gray polyamide (PA6) housing carries two rows of female socket contacts on a 0.138" (3.50mm) pitch, terminated by crimp — no soldering, no staking, just a clean terminal insertion and a latch holder that locks the pair together. The sealed construction and -40°C ~ 125°C operating range put this squarely in underhood automotive, off-road equipment, and industrial control cabinets where an unsealed header would corrode in a season.
What the Sealed Housing and Latch Holder Buy You
The sealed feature means the interface between mated halves keeps out splash, dust, and pressure-wash spray — no secondary boot or potting required for IP-rated applications. The 0.138" (3.50mm) pitch is wider than a signal-level 2.54mm header, which means each contact has more plastic between it and the next — better creepage for the 14V/24V nominal automotive bus, and room for the wire seal that makes the sealed rating real.
Sourcing This Part for a BOM Line
The lifecycle record shows an Active status — no NRND notice, no last-time-buy date on the horizon. This is a current-production part that crosses to the standard MX150 receptacle housing family. It ships without contacts (notes the contact type, but the connector body and terminals are separate line items); order the matching 160074-series crimp terminals separately.
