TC-400-NF-X N Female Crimp/Solder Connector for LMR-400 coaxial cable
TC-400-NF-X Connector is a heavy duty N-Type Female (jack) connector specifically designed for the reliable termination of LMR-400 and similar flexible low-loss coaxial cable. As part of the traditional TC Series, this connector features a solder pin connection, which is often preferred for applications using stranded center conductors or where maximum mechanical and electrical integrity is required. It provides a durable, weatherproof, and high performance female connection point for systems operating up to 6 GHz.
Features
- LMR-400 Optimized: Precision engineered for the larger diameter and superior low-loss characteristics of LMR-400 coaxial cable, ensuring optimal signal integrity and power handling.
- Solder Pin Connection: The traditional solder inner contact is ideal for installations where maximum durability and a low-resistance electrical connection are critical, especially with stranded center conductors.
- High-Frequency N-Type: The robust, medium-sized threaded coupling mechanism is renowned for its durability and excellent electrical characteristics, supporting frequencies up to 6 GHz.
- Weatherproof Design: The N-Type interface provides a reliable, threaded, weatherproof coupling when mated, making it suitable for both indoor and outdoor rated systems.
- Rugged Materials: Constructed from brass with nickel body finish and a gold-plated center pin for exceptional corrosion resistance and a long lifespan.
