USB C to USB B cable for printers and peripherals

This three-metre cable links USB 2.0 Type-B devices such as printers, scanners or external drives to a USB-C or Thunderbolt 3 host. The 480 Mbit/s bandwidth matches the USB 2.0 specification. It suits users who need a longer reach than standard cables provide.

Nickel-plated connectors

Nickel plating on the 24-pin USB-C and 4-pin USB-B plugs resists corrosion through repeated insertion. The PVC jacket protects the 23 and 28 AWG conductors while remaining flexible. No driver installation is required; the connection works immediately on supported operating systems.

Straight male-to-male layout fits tight ports

Both connectors are straight, allowing the cable to sit flush against equipment backs or dock stations. The three-metre length gives freedom to place peripherals away from the host without stretching. It does not support USB 3.x or Thunderbolt 4 speeds, so buyers needing higher throughput should select a different cable.

Questions about this item

Will the nickel-plated connectors on this USB2CB3M cable need cleaning or replacement over time?

The connectors are nickel-plated for corrosion resistance and do not require scheduled cleaning or replacement under normal use.

What limits the data rate when this cable runs at full 480 Mbit/s for long periods?

The USB 2.0 specification caps the transfer rate at 480 Mbit/s, so the protocol itself is the limiting factor during sustained transfers.

Does the 3 m PVC jacket and 23/28 AWG wire gauge cause noticeable heat or power loss during all-day use?

The cable is rated for USB 2.0 power delivery; the PVC jacket and wire gauge keep voltage drop within spec, so heat and power loss remain minimal during continuous operation.
