ACT RJ11 (6P/4C) modulaire connector for round cable with stranded conductors

The ACT RJ11 (6P/4C) Modular Connector TD104R is designed for terminating round telephony and low-speed data cables with stranded conductors. Supplied in packs of 25, each connector provides the standard 6-position, 4-conductor configuration used in many telephone and voice/data installations. The connector body and contact arrangement are compatible with common RJ11 sockets and deliver a compact, reliable connection for wall plates, cord sets, and inline cable joins.

Advantages

These RJ11 modular connectors are intended for stranded round cables and offer a consistent contact interface that reduces connection failures. The connectors are produced to a uniform physical size to ensure compatibility with existing RJ11 jacks and housings. Packaging in sets of 25 supports small installations and repairs while keeping spares readily available. The design facilitates straightforward crimping and insertion, enabling efficient termination in field or workshop environments.

Suitable for

• Telephone handsets and wall jacks
• Low-speed data connections and analog devices
• Field repairs and small-volume installation projects
• DIY wiring and cord set assembly

Key specifications

• Connector type: 6-position, 4-conductor (6P/4C) modular plug
• Cable compatibility: round cables with stranded conductors
• Quantity per pack: 25 connectors
• Contact arrangement: four active contacts for voice/data pairs
• Compatibility: fits standard RJ11 sockets and housings

How to use

Strip the cable jacket to expose the stranded conductors, untwist and arrange the conductors in the required wiring order, then insert them fully into the connector until the conductor ends reach the contact ends. Use a compatible crimping tool or insertion tool designed for RJ11 modular plugs to secure the wires and compress the connector's strain relief onto the cable. Verify each connection with a handset, telephone device, or meter to confirm continuity and correct wiring before finalizing the installation.

Recommendations

For reliable terminations, use a quality RJ11 crimp tool and avoid excessive stripping of conductor insulation. Keep spare connectors from the same pack for uniform contact characteristics across an installation. Where line quality is critical, test completed cables with a line tester and re-terminate any connections that show intermittent contact or high resistance.
