TC-400-NFC N-Female Coaxial Connector for LMR-400 Times Microwave
TC-400-NFC is a robust, high-performance Type N Female (Jack) coaxial connector engineered for seamless integration with LMR-400 series cables and similar high-quality coaxial cables. It’s the ideal choice for demanding applications where signal integrity and reliability are paramount.
- Exceptional RF Performance: Low VSWR (Voltage Standing Wave Ratio) of <1.25:1 up to 2.5 GHz ensures minimal signal reflection and maximum power transfer.
- Durable & Weatherproof: As a medium-size RF connector, the Type N interface is renowned for its durability and weatherproof design, making it suitable for both indoor and harsh outdoor environments.
- High-Quality Plating: Features a Gold-plated center contact for enhanced mate/de-mate life and a Nickel or Alballoy body finish for superior corrosion resistance.
- Secure Connection: Utilizes a reliable threaded coupling mechanism that is fully interchangeable with N-Type connectors made to the MIL-C-39012 specification.
- Solder-Pin Design: The solder-on center contact makes it a perfect option for cables with stranded center conductors, ensuring a secure and low-resistance connection.
- Easy Termination: Designed for straightforward field installation with a clamp-on outer contact (braid) for efficient and reliable termination.
