Frequently Asked Questions
How is the internal wire gauge structured in this USB 2.0 Type-C cable assembly to balance power and data?
This cable utilizes a hybrid wire architecture consisting of 24AWG x 2C conductors dedicated to the VBUS power path (Pins A4+A9+B4+B9) and a 30AWG x 1PR twisted pair for the USB 2.0 differential data lines (D+ on Pin A6, D- on Pin A7). The heavier 24AWG power cores minimize DC voltage drop over the 1000mm length, while the 30AWG twisted pair maintains 90-ohm differential impedance for stable 480Mbps data transmission.
What materials are used for the cable jacket and connector strain relief to ensure mechanical durability?
The cable features a 4.0mm OD black TPE (Thermoplastic Elastomer) jacket, which offers superior flexibility and abrasion resistance compared to conventional PVC. At both terminations, a two-stage molding process combines a rigid PP (Polypropylene) inner mold to encapsulate the solder joints with a flexible 35P black PVC outer overmolding, preventing wire pull-out and flex fatigue.
What electrical and quality inspections are performed on each USB-C cable assembly prior to shipping?
Every assembly undergoes 100% electrical testing for open circuits, short circuits, and miswires, alongside a dielectric withstanding voltage test at DC 300V for 0.01 seconds. It guarantees a maximum conductor resistance of 5 Ohms and a minimum insulation resistance of 10M Ohms, followed by a 100% final dimensional and visual inspection before individual bag packaging.
Overview and Application Notes
This industrial-grade USB 2.0 Type-C Male to Type-C Male cable assembly is engineered for reliable power delivery and stable High-Speed 480Mbps data transmission across commercial, industrial, and embedded electronics. Constructed with a hybrid conductor core featuring 24AWG power wires and a 30AWG twisted data pair, it ensures minimal voltage drop alongside solid signal integrity. Encased in a flexible 4.0mm outer diameter (OD) black TPE jacket with 35P PVC overmolded strain reliefs, this 1000mm cable assembly resists mechanical fatigue, abrasion, and repeated bending in demanding OEM applications.

Engineering Specifications & Integration
Designed for seamless integration with standard USB Type-C female receptacles on PCBs, single-board computers (SBCs), and industrial enclosures, this cable maps VBUS across pins A4+A9+B4+B9 (Red) and Ground across A1+A12+B1+B12+Shield. Differential data lines are routed to A6 (D+, Green) and A7 (D-, White), with the Configuration Channel (CC) terminated on pin A5 (Black) for reliable device role detection. The compact overmolded plug profile (6.8 ± 0.2mm thickness, 26.5mm Ref. length) guarantees clearance in tightly spaced I/O panels. Rated for a maximum conductor resistance of 5 Ohms, minimum insulation resistance of 10M Ohms, and dielectric withstanding voltage of DC 300V/0.01sec.
