TC-400-BM-75-X

TC-400-BM-75-X BNC Male Straight 75 Ohm TC Connector for LMR-400-75 Coaxial Cable

TC-400-BM-75-X Connector is a high-precision, 75 Ohm BNC Male (plug) connector specifically engineered for the reliable termination of the large, low-loss LMR-400-75 coaxial cable. Crucial for professional broadcast and video systems, this connector is designed for perfect 75 Ohm impedance matching up to 2 GHz, ensuring the highest integrity for digital video signals (SDI, HD-SDI). Part of the trusted TC (Times Crimp) series, it features a traditional solder-on center pin for the most robust electrical connection, making it ideal for stranded center conductors and permanent installations.

Key Features & Precision Engineering

• True 75 Ohm Impedance: Crucial for video and broadcast applications, maintaining a VSWR < 1.1:1 up to 2 GHz for minimal signal reflection and pristine image quality.
• LMR-400-75 Optimized: Engineered specifically for the larger LMR-400-75 coaxial cable, maximizing the benefit of its superior low-loss performance over long cable runs.
• BNC Bayonet Coupling: Features the classic quick-connect/disconnect bayonet mechanism, providing a reliable, positive lock with just a quarter-turn.
• Solder Center Pin: Provides the most durable electrical connection, especially suitable for the stranded conductors often found in LMR-400-75, ensuring maximum pull strength and reliability.
• Superior Corrosion Resistance: Finished with Albaloy/Tri-Plate plating (White Bronze), which provides market-leading performance against corrosion and salt fog, enhancing reliability in challenging environments.
• No Braid Trim Design: Simplifies cable prep and ensures consistent, superior performance by eliminating the braid trim step.

TC-400-BM-75-X Detailed Technical Specifications

Typical Applications

The combination of the rugged BNC interface, 75 Ohm impedance, and LMR-400-75 compatibility makes the TC-400-BM-75-X essential for:

• Broadcast Video: Creating high-integrity jumpers and feeder cables for SDI/HD-SDI video signals in studios and field production.
• CATV & MATV Systems: Head-end and backbone connectivity requiring high-fidelity 75 Ohm signaling.
• Specialized Test Leads: Precision 75 Ohm test and measurement applications.
• Long-Distance CCTV: Maintaining video quality over extended security and surveillance camera runs.

Installation & Recommended Tooling

Installation requires a precise cable strip and crimp, along with soldering the center pin:

• Crimping Tool: The required hex die size (Times Microwave CT-400/300 tool) is mandatory for securing the ferrule.
• Cable Prep Tool: The dedicated CST-400-75 strip tool is essential for achieving the exact conductor, dielectric, and jacket exposure.
• Soldering Iron: Required for securely attaching the center pin.
