Delphi Aptiv 54200311 3-Way Female Apex 2.8mm Sealed Plug

The Component: Genuine Delphi / Aptiv OEM 3-position sealed female receptacle housing / Premium Apex 2.8mm Series Inline Plug Assembly / Features a high-current 3-way single-row layout matrix / Integrated red Connector Position Assurance (CPA) locking thumb slide / Contrast blue internal front-loading terminal carrier interface / High-durability natural thermoplastic construction / Component Part Number: 54200311 / Aptiv Reference: 54200311.

Applications & Fitment: Engineered to establish a rugged, heavy-duty electrical link capable of handling elevated current densities in highly exposed automotive and commercial vehicle installations. This authentic 3-pin Delphi Apex series female plug is widely deployed across global automotive wiring systems, motorsport electrical assemblies, and industrial marine looms. Utilizing the robust 2.8mm flat tab contact footprint in a straight 1x3 single-row matrix, it is specifically designed to interface with demanding medium-to-high current powertrain components, including heavy-duty engine coolant temperature sensors, auxiliary cooling fans, fuel pumps, pressure switches, and windshield wiper motor assemblies. The integrated red CPA slider mechanism offers crucial secondary safety validation by mechanically preventing the primary lever thumb-latch from releasing during intense vibration profiles or severe harness pulling actions. Its internal blue front alignment plate secures individual terminals tightly behind the mating surface, ensuring perfect pin registration during connection cycles. Complete barrier isolation against moisture ingress, chemical solvents, road salts, and high-pressure spray is maintained by an integrated rear multi-hole wire seal mat compressed by a black polymer end-cap. A critical item for professional harness manufacturers, specialist auto-electricians, and wholesale trade distributors.
