TC-400-SM-X

TC-400-SM-X SMA Male Crimp Connector for LMR-400 Coaxial Cable

TC-400-SM-X Connector is a high-performance SMA Male (plug) coaxial connector specifically engineered for terminating LMR-400 and similar 400-series flexible low-loss coaxial cable. As a traditional solder-pin connector, it provides a highly robust and reliable connection, perfect for professional, permanent installations that demand maximum electrical performance up to 8 GHz. It is the ideal choice for creating durable, low-loss jumpers and antenna feeders using the larger LMR-400 coaxial cable.

Key Features & Advantages

• Optimized for LMR-400: Perfectly matched to the electrical and physical requirements of LMR-400 coaxial cable, ensuring the cable’s inherent low loss and superior performance are maintained.
• SMA Interface: Provides the compact, high-frequency SMA threaded coupling, essential for cellular, GPS, microwave, and compact equipment.
• Solder Pin Center Contact: Utilizes a traditional solder method for the inner contact. This provides the most mechanically secure and electrically consistent connection, particularly recommended for stranded center conductors.
• High-Frequency Capability: Engineered for reliable operation across its range, supporting applications up to an impressive 8 GHz.
• Durable Construction: Built with brass and plated with White Bronze (Tri-Metal) for the body and Gold on the center pin, ensuring long life and excellent corrosion resistance.

TC-400-SM-X Detailed Technical Specifications

Typical Applications

The TC-400-SM-X is essential for creating robust, low-loss SMA connections in:

• Wireless Infrastructure: Connecting antennas, base stations, and repeaters using LMR-400.
• Microwave & Satellite Communications: Used in systems requiring high-frequency signal integrity.
• Test & Measurement: Creating high-quality, durable test leads for laboratory and field equipment.
• General RF Interconnects: Any application that demands the high performance of LMR-400 with a compact SMA interface.

Installation & Recommended Tooling

The “TC” series requires a precise strip and soldering for the center pin:

• Crimping Tool: The required hex die size (typically .429″ HEX) is necessary for securing the ferrule onto the cable braid.
• Cable Prep Tool: The dedicated CST-400 prep tool is highly recommended to achieve the exact strip dimensions for the solder pin.
• Soldering Iron: A clean, hot soldering iron and proper solder are required to affix the center pin to the conductor.
