Professional custom cable assembly service. We manufacture high-quality wire harnesses bridging Molex 51021 (Micro-Fit 3.0) connectors to Molex 6471 terminals. Get a reliable, custom-tailored solution.

Bridging Your Interconnect Needs

Our specialized custom cable assembly service provides a seamless and reliable bridge between two proven Molex technologies: the Molex 51021 Micro-Fit 3.0 connector system and the Molex 6471 discrete terminal system. We engineer and manufacture complete wire harnesses that translate the compact, multi-circuit power of the Micro-Fit platform to the versatile, discrete point-to-point connections of the 6471 receptacle. This eliminates your design and assembly challenges, delivering a ready-to-install, robust interconnect solution.

Key Features & Benefits of Our Custom Service:

Precision Engineered Solution: We handle the entire process, from design support to production, ensuring perfect compatibility between the 51021 connector and 6471 terminals.

Molex 51021 (Micro-Fit 3.0) Source End:

Compact 3.00mm pitch for space-saving PCB or device entry.

High-current capacity (5.0A per circuit).

Features Terminal Position Assurance (TPA) for secure terminal retention.

Fully polarized housing prevents mis-mating.

Molex 6471 Terminal Destination End:

Discrete, high-reliability female receptacles.

Designed for press-fitting into PCB holes or use with compatible housings.

Excellent for making secure, permanent solderless connections to boards or other 6471-compatible male pins.

Full Customization: We tailor every aspect to your requirements:

Wire Gauge & Length: Specify exact AWG (e.g., 20, 22, 24) and harness length.

Conductor Count & Color: Choose the number of circuits and wire color coding for easy installation and troubleshooting.

Shielding & Jacketing: Options include overall shielding for EMI protection and various jacket materials for durability and flexibility.

High-Quality Manufacturing: Utilizing automated crimping machines to ensure perfect, gas-tight connections on every terminal, guaranteeing electrical reliability and mechanical strength.

Applications:

This type of custom harness is ideal for applications requiring a transition from a compact multi-pin connector to individual board-level points:

Power Supply Units (PSUs): Distributing power from a main connector to various points on a control board.

Industrial Automation & Controls: Connecting sensors, drives, and I/O modules.

Telecommunications Equipment: Internal wiring for servers and network hardware.

Medical Device Interconnects: Where reliable, custom-length wiring is critical.

Technical Specifications (Customizable):

Connector A: Molex 51021 Series (Micro-Fit 3.0, e.g., 51021-0600 for a 6-circuit receptacle)

Terminal B: Molex 6471 Series (Female Receptacle)

Current Rating: Up to 5.0 A (dependent on wire gauge)

Voltage Rating: Up to 250 V

Wire Type: PVC or other specified insulation, custom AWG.

Termination: Precision crimped.
