StarTech USB2AC2M USB-A to USB-C Cable, 6.6 ft, USB-IF Certified

Overview

The StarTech USB2AC2M is a 6.6 ft (2 m) USB 2.0 Type-A to USB Type-C cable built for integrators and IT teams who need a reliable, standards-verified connection between a host computer and USB-C peripherals — without the intermittent failures or charge-only limitations that plague generic cables. At 480 Mbps, this is a data-capable cable suitable for connecting USB-C webcams, card readers, scanners, and other peripherals to standard USB-A ports on workstations, NVRs, and embedded systems.

The USB-IF certification is the key differentiator here. It means the USB2AC2M has been independently tested and verified against the USB Implementers Forum specification — not just labeled as compliant. For enterprise deployments where IT policy requires certified accessories, this matters at procurement time.

Key Features

• USB-IF Certified: Independent third-party verification against the USB Implementers Forum specification means this cable has passed standardized electrical and mechanical testing — not just a self-declared compliance label. This matters in IT procurement environments that require documented certification for peripheral accessories.
• 480 Mbps USB 2.0 Data Rate: Supports full USB 2.0 throughput, which covers the vast majority of USB-C peripherals: webcams, barcode scanners, card readers, audio interfaces, and low-bandwidth serial devices. If you're connecting USB 3.x or Thunderbolt peripherals, you'll need a different cable — this one tops out at USB 2.0 speeds by design.
• 6.6 ft (2 m) Length: Long enough to route from a wall-mounted or under-desk workstation to a peripheral on the desk surface without tension on connectors. Two meters is the practical sweet spot for most fixed-workstation USB peripheral runs — enough slack for clean cable management without excess that pools on the floor.
• 22/30 AWG Conductor Gauge: The 22 AWG power conductors support both data and charging at USB 2.0 levels. The heavier power gauge relative to a pure data cable means the USB2AC2M can handle peripheral charging functions alongside data transfer without voltage drop issues over the 2 m run.
• Aluminum-Mylar Foil + Braid Shielding: Dual-layer shielding (foil plus braid) reduces susceptibility to EMI — relevant in environments with dense wireless activity, motor controllers, or adjacent power cabling. A single-layer foil-only cable is adequate for clean environments; the braid layer adds protection where interference is a real concern.
• Nickel-Plated Connectors: Nickel plating provides corrosion resistance and consistent contact resistance over repeated mate/unmate cycles. More relevant in industrial or light commercial environments than a clean office, but it contributes to long-term connector reliability in any fixed installation.
• PVC Jacket: The PVC outer jacket is flexible enough for routing through cable managers and around desk edges without kinking. It is not rated for in-wall or plenum use — route externally or inside open cable trays.
• 2.5 oz (70 g) Weight: Light enough that connector stress on the USB-C port is minimal even without cable tie-off, though anchoring the cable near the device is still good practice in any permanent installation.

Integration and Compatibility

The USB2AC2M connects any USB 2.0 Type-A host port to a USB-C device. Compatible hosts include Windows, macOS, and Linux workstations, as well as embedded computing platforms and NVR/DVR units that expose USB-A ports for peripheral connections. On the device side, it works with any USB-C peripheral that operates at USB 2.0 speeds — note that some USB 3.x and USB4 devices will negotiate down to USB 2.0 speeds on this cable, which may be acceptable depending on your bandwidth requirements.

This cable does not support video output (DisplayPort Alt Mode, Thunderbolt, or MHL), USB Power Delivery at high wattage, or USB 3.x/USB4 data rates. If your use case requires any of those, specify a cable rated for those protocols before purchase.

For deployments pairing USB-C cameras or scanners with a network video recorder that has onboard USB host ports, or connecting peripherals to a dedicated surveillance workstation, the USB2AC2M covers standard device communication at full USB 2.0 throughput. Integrators sourcing USB cabling alongside StarTech connectivity accessories will find this fits within the same procurement family.

Frequently Asked Questions

Q: Is the StarTech USB2AC2M USB-IF certified?

A: Yes. The USB2AC2M carries USB-IF certification, meaning it has been independently tested and verified against USB Implementers Forum standards — not self-declared compliance.

Q: What data transfer speed does the USB2AC2M support?

A: The USB2AC2M supports USB 2.0 at 480 Mbps. It does not support USB 3.x, USB4, or Thunderbolt data rates.

Q: Can the USB2AC2M be used for charging as well as data transfer?

A: Yes. The 22 AWG power conductors support USB 2.0 level charging alongside data transfer. It does not support USB Power Delivery high-wattage profiles.

Q: Is the USB2AC2M suitable for in-wall installation?

A: No. The PVC jacket is not rated for in-wall or plenum installation. Route externally using cable trays or surface raceways.

Q: Does the USB2AC2M support video output or DisplayPort Alt Mode?

A: No. This is a USB 2.0 data and power cable only. It does not support video output, DisplayPort Alt Mode, Thunderbolt, or MHL.

Q: What type of shielding does the USB2AC2M use?

A: Dual-layer shielding: aluminum-Mylar foil plus braid. This provides better EMI rejection than foil-only cables, which is relevant in electrically noisy environments such as industrial floors or areas with dense wireless infrastructure.

James Everett

The detail I keep coming back to on the USB2AC2M is the dual-layer shielding — aluminum-Mylar foil combined with a braid. Most commodity USB-A to USB-C cables ship with foil only, which is fine in a clean office but starts showing its limits when you're routing alongside power distribution, near motor drives, or through a server room with dense RF. For integration work in light industrial or mixed-environment security installations, that extra braid layer is the difference between a stable device connection and an intermittent fault you'll spend an hour chasing.

Technical Highlights:

• USB-IF Certification: Independently verified against USB Implementers Forum specifications — not a manufacturer self-declaration. Relevant when procurement requires documented compliance for accessories deployed in commercial or government environments.
• 22/30 AWG Conductor Geometry: Heavier 22 AWG power conductors support charging alongside data at USB 2.0 levels over the full 2 m run without meaningful voltage drop. The 30 AWG signal conductors keep the cable flexible without sacrificing data integrity at 480 Mbps.
• 480 Mbps USB 2.0 Throughput: Sufficient for the majority of USB-C peripherals in security and automation deployments — webcams, card readers, barcode scanners, and serial-to-USB converters all operate well within this bandwidth envelope.

Deployment Considerations:

• At 2 m and 2.5 oz, this cable is well-suited for fixed desk or equipment-rack peripheral runs where you need enough length to route cleanly without connector stress. Anchor near the USB-C device end if the peripheral will be handled regularly.
• Hard limit: USB 2.0 only. If you're connecting a USB 3.x device that requires higher bandwidth — an external SSD, a high-frame-rate USB camera, or a USB 3.x hub — the USB2AC2M will negotiate down to 480 Mbps and the device will underperform. Specify a USB 3.x-rated cable for those scenarios before deployment.

For fixed-workstation security deployments connecting USB-C scanners, access card readers, or enrollment stations to a USB-A host port — particularly in environments where EMI from nearby power infrastructure is a consideration — the USB2AC2M is the right pick over a generic unshielded cable.
