MOLEX 5557 6-Pin to XH / Spade Terminal Wire Harness

Our product is a customized adapter wire harness based on the widely recognized MOLEX 5557 series 6-pin connector on one end, transitioning to an XH terminal or spade terminal on the other end. It is designed specifically for electrical signal or power conversion connections between different interface standards and is widely used in desktop computers, server equipment, LED lighting control systems, power adapters, robotics control modules, and internal or external wire connections within various embedded electronic devices. The MOLEX 5557 series connector is one of the most widely used classic connector families in the industry, well known for its sturdy structure, reliable contact, and smooth insertion/removal — particularly enjoying strong market recognition and widespread adoption in the computer hardware and power connection fields, making it a preferred interface choice for many equipment manufacturers when designing their products.
One end of this product features a standard MOLEX 5557 6-pin female or male connector (selectable according to the customer's actual mating requirements), with pin spacing, housing dimensions, and latch structure manufactured strictly to original MOLEX factory standards, ensuring full compatibility with standard MOLEX 5557 series mating connectors (such as MOLEX 5556 series male connectors) available on the market, with smooth insertion and secure latching, avoiding compatibility issues such as improper mating or loosening that could arise from non-standard customization. The other end can be transitioned, according to actual customer requirements, to either an XH series terminal (using the industry-standard 2.5mm pitch design, offering convenient insertion/removal and a secure connection, widely used for board-to-board or board-to-wire connections in electronic devices) or a spade terminal (such as common 4.8mm or 6.3mm specifications, suitable for quick connection with switches, relays, fuse holders, and other components) — truly enabling flexible conversion and matching between different interface standards.
The wire section in the middle of the harness is manufactured using high-quality copper core conductors, with wire gauge selectable according to the customer's actual current-carrying requirements, wrapped in a wear-resistant, aging-resistant, and flame-retardant insulation sheath, fully ensuring the electrical safety and mechanical durability of the harness over long-term use. We support in-depth customization of the connector's male/female configuration, pin sequence, wire color assignment, overall harness length, and the specific type and specification of the adapter terminal according to each customer's actual device interface standards, truly achieving precise "one-to-one" matching. During production, we strictly implement continuity testing, insulation resistance testing, plug-cycle life testing, and visual inspection as part of a multi-layered quality control process, ensuring every harness meets relevant industry standards before shipment. This enables us to provide customers with a stable, reliable, and highly compatible customized adapter wire harness solution, serving fast-growing industries such as computer hardware, consumer electronics, lighting control, and smart device manufacturing.
