ACT TD4104 USB-A socket-to-socket coupler

The ACT USB-A female-female coupler TD4104 is a compact inline adapter designed to join two USB-A cables. Its flat construction and white finish make it suitable for discreet installations in home or office environments. The coupler provides a direct female-to-female connection for standard USB-A cables, allowing you to extend cable length without introducing active electronics or signal conversions.

Advantages

The coupler offers a simple, passive connection method that maintains the original USB-A cable form factor. Its slim profile reduces bulk at connection points, and the neutral white color blends with most cable runs and wall plates. As a passive mechanical adapter, it requires no power and does not alter cable signaling, supporting straightforward extension of USB-A leads.

Suitable for

• Extending the reach of USB-A cables between devices and peripherals
• Temporary connections in meeting rooms, classrooms, or workstations
• Linking two USB-A extension cords to achieve a custom cable length

Key specifications

• Connector type: USB-A female to USB-A female
• Construction: flat inline coupler
• Color: white
• Pack quantity: 1 piece

How to use

Insert the male USB-A plug of the first cable into one side of the coupler and the male USB-A plug of the second cable into the opposite side until each plug is fully seated. Ensure connectors are aligned and do not force angled insertion. The coupler is passive; no configuration or power is required. After joining, verify device communication and power delivery as needed, keeping in mind that overall cable length and quality can affect USB performance.

Recommendations

Use the coupler for short to moderate cable extensions and non-critical data links. For high-speed USB applications or long-distance runs, consider using a single continuous USB cable of the appropriate spec or an active repeater/extender to maintain signal integrity and power delivery.
