Sealed 8-Circuit Receptacle with Connector Position Assurance
The Molex MX150 1600783016 is an 8-circuit, 2-row receptacle from the MX150 160078 series, designed for sealed wire-to-wire interconnects in demanding environments. It carries a 0.138" (3.50 mm) pitch, uses female socket contacts terminated by crimp, and mounts free-hanging (in-line). The black glass-filled PA6 housing includes Connector Position Assurance (CPA) and a latch holder fastening system, confirming the connector is fully mated and locked — critical for applications where vibration or thermal cycling could otherwise back a contact out. The sealed construction and CPA make this receptacle suited for underhood automotive harnesses, off-highway equipment, and any power or signal interconnect exposed to moisture, dust, or washdown.
Pitch, Sealing, and Temperature Class
At 3.50 mm pitch, this receptacle provides adequate creepage for the voltage levels typical of 12 V and 24 V automotive systems while keeping the connector body compact for harness routing in tight bays. The sealed housing (listed as a feature) blocks ingress from road spray, coolant splash, and pressure washing — no separate boot or overmold required for IP-rated performance when mated with the matching MX150 plug. The -40°C to 125°C rating is the full operating band, not storage. That means the connector carries rated current across the automotive temperature class 3 range, covering both cold-soak starts and underhood heat soak. The glass-filled PA6 insulation material holds dimensional stability through thermal cycling without warping the latch or seal surfaces.
