DELTA BNC-W/S BNC Male Twist-On Connector for RG59 Coaxial Cable, 75 Ohm, Nickel-Plated Brass, Tool-less Installation

For CCTV installers and security technicians, terminating RG59 coax in the field can be slow and error-prone. The DELTA BNC-W/S twist-on BNC male connector eliminates the need for crimp tools—just strip, twist, and go. Its nickel-plated brass body and PTFE insulator ensure reliable 75-ohm signal integrity for analog video up to 1 GHz, making it a dependable choice for surveillance and broadcast applications.

Key specifications

Why choose it

This connector is built for speed and repeatability. The twist-on design cuts installation time dramatically compared to crimp or compression connectors, while the nickel-plated brass construction resists corrosion and provides a secure mechanical fit. The PTFE insulator maintains stable impedance and low signal loss across the supported frequency range, ensuring clear video transmission in CCTV and security systems.

Ideal use cases

• CCTV and video surveillance camera connections
• Analog video distribution in security installations
• Field termination of RG59 cable without specialized tools
• Maintenance and repair of existing coaxial runs
• Broadcast and AV applications requiring 75-ohm BNC terminations

Good to know

The connector is designed for RG59 cable only; using it with other cable types may result in poor performance or unreliable connections. It supports up to 500 mating cycles, making it suitable for environments where connections are periodically disconnected and reconnected. No crimping tool is required—just strip the cable to the recommended dimensions and twist the connector body onto the prepared end.
