USB4 Cable 40Gbps USB-C to USB-C 240W PD | SKW USB-4001A-019
Product Details
USB4 40Gbps Performance Architecture
The SKW USB-4001A-019 is a USB4 Type-C cable engineered for environments where bandwidth, power delivery, and video throughput must coexist on a single connection path. Built around the USB4 specification, it delivers up to 40Gbps symmetric data transfer — sufficient for dual 4K displays, external NVMe arrays, or Thunderbolt 3/4 peripheral chains without protocol negotiation overhead.
Bandwidth Allocation and Protocol Support
Power delivery reaches 240W under USB PD 3.1 Extended Power Range, enabling this cable to charge high-performance laptops, mobile workstations, and all-in-one systems that previously required proprietary DC barrel connectors. The integrated E-marker chip communicates cable capabilities to host and device controllers, ensuring the connected devices negotiate the correct voltage and current profile rather than defaulting to a safe but slow 60W fallback.
DisplayPort 2.0 Alt Mode Capabilities
Video output supports DisplayPort 2.0 Alt Mode at resolutions up to 8K@60Hz or 4K@144Hz, making it suitable for professional color-critical workflows, digital signage controllers, and next-generation gaming setups. The cable maintains backward compatibility with USB 3.2, USB 2.0, and Thunderbolt 3 hosts and peripherals.
240W USB PD 3.1 Power Delivery
Construction uses a braided nylon outer jacket rated for 10,000+ bend cycles, paired with aluminum alloy connector housings that dissipate heat from sustained high-current operation. Internal conductors are arranged with individually shielded twisted pairs to minimize crosstalk at 40Gbps signaling rates. Strain relief molding at the connector-cable junction prevents fatigue failure from repeated flexing in desk-mounted or rack-mounted deployments.
E-Marker Chip Function and Negotiation
For B2B procurement, the USB-4001A-019 offers advantages over generic USB-C cables that lack E-marker identification or use undersized power conductors. Each unit undergoes continuity testing, hi-pot dielectric withstand verification, and signal integrity validation at rated bandwidth before shipment. Cable parameters are laser-marked on the jacket for traceability in field installations.
