Times Microwave EZ-195-SM-X SMA Male Straight Connector for LMR-195 Coaxial Cable
EZ-195-SM-X Connector is a high-performance SMA Male (plug) connector specifically engineered for rapid, reliable termination of LMR-195 and similar flexible low-loss coaxial cable. Part of the industry-leading EZ-Fit series, this connector is designed to deliver superior electrical performance up to 6 GHz while drastically simplifying the installation process. It is the ideal choice for compact RF devices and systems where space and quick, flawless assembly are crucial.
Key Features & Advantages
- SMA Form Factor: Provides a small, high-frequency interface widely used in cellular, GPS, and compact wireless systems.
- EZ-Fit™ Technology: Features a solderless, spring-finger inner contact design, eliminating the need for soldering the center pin and minimizing installation time and potential human error.
- Superior VSWR Performance: Engineered for optimal impedance matching, offering excellent Voltage Standing Wave Ratio (VSWR) across the operating frequency range up to 6 GHz.
- No Braid Trim Design: Simplifies cable preparation by removing the requirement to trim the coaxial cable braid, which helps ensure consistent electrical integrity and reduces FOD (Foreign Object Debris).
- Rugged and Reliable: Built with a durable brass body and finished with nickel plating for excellent environmental protection and long-term reliability.
