The 5055700400 model is a precision-engineered 4-pin female receptacle housing designed specifically for demanding wire-to-wire automotive architectures. Molded in a clean, natural color for immediate visual inspection on fast-paced assembly lines, this connector housing delivers a rigid, burr-free tactile feel that ensures confident handling. When operators engage the mating components, the housing produces a distinct, audible click—a critical sensory confirmation that the positive locking mechanism has been fully and securely activated. This physical feedback eliminates guesswork and significantly reduces the risk of incomplete connections during complex wiring tasks.
Automotive environments expose electrical systems to harsh elements, from road salts to heavy moisture. When properly assembled with the appropriate wire seals, this housing architecture supports IP67 and IP68-level waterproof and dustproof sealing. This exceptional environmental defense provides outstanding anti-corrosion properties, ensuring that the internal tin contacts remain uncontaminated and fully operational even after years of exposure to challenging weather conditions.
To combat the intense, continuous vibrations generated by engines and uneven road surfaces, this connector is equipped with a robust Terminal Position Assurance (TPA) capability and a secure positive locking mechanism. The TPA guarantees that all inserted terminals are fully seated and physically locked into their correct positions, preventing terminal back-out. Furthermore, the intelligent polarity keying design acts as a physical barrier against mis-mating, safeguarding the circuitry from accidental reverse-insertion damage.
Engineered to accommodate specific AWG wire ranges, the housing geometry ensures optimal contact pressure for stable, high-power transmission. This precise internal alignment minimizes contact resistance, allowing for consistent current and voltage delivery without dangerous thermal buildup. Constructed from advanced, flame-retardant thermoplastic materials, the housing maintains strict dimensional stability across an extreme temperature spectrum of -55°C to +150°C. It fully complies with rigorous glow-wire testing standards, adding a crucial layer of fire safety to the vehicle's electrical network.

A: Yes, samples are available to help you evaluate the connector's tactile locking feel and dimensional accuracy. Our company policy requires that all customers initially cover the sample fee and associated shipping costs. However, as a commitment to our partnership, this sample fee will be fully returned to you as a credit when you place your first official production order.
A: To maintain efficient production cycles while remaining accessible for specialized projects, the Minimum Order Quantity (MOQ) of our products is set at 300 pcs for one specific model and one size (such as the 4-position natural housing). This ensures consistent batch quality and optimal material utilization.
A: Absolutely. We understand the importance of optimizing freight logistics. You can securely mix multiple connector models, wire harnesses, or other components within a single container (up to 1X40HQ). Our packaging team will ensure all standard cartons are properly palletized and secured for safe transit.
A: Certainly. We provide extensive OEM and ODM services designed to elevate your brand visibility. This includes custom logo printing, specialized gift box creation, and tailored master carton design. If you require specific labeling for assembly line scanning or inventory management, our team will integrate those requirements seamlessly.
A: Under normal conditions, our standard delivery time is 30-40 days after the receipt of your deposit and the final confirmation on all design specifications. This timeline allows us to conduct thorough quality assurance testing, including glow-wire and dimensional checks, before dispatching your order.
A: Basically, our primary and most efficient payment method is T/T (Telegraphic Transfer). This ensures secure and traceable international transactions. If you have any specific financial demands or require alternative arrangements for large-scale projects, please feel free to contact us to discuss tailored solutions!
