EZ-240-UM-X UHF Male Crimp/Captivated Connector for LMR-240 coaxial cable
EZ-240-UM-X Connector is a high-performance UHF Male (PL-259) connector specifically engineered for the rapid, reliable termination of LMR-240 and similar flexible low-loss coaxial cable. As a premium component of the revolutionary EZ-Fit series, this connector provides the traditional UHF interface widely used in amateur radio, marine, and legacy RF systems, combined with the convenience of solderless installation.3 It is the ideal choice for creating durable, low-frequency cable assemblies with the performance benefits of LMR-240 coaxial cable.
Key Features & Advantages
- UHF (PL-259) Interface: Features the popular, traditional UHF Male (Plug) interface, essential for amateur radio (Ham), marine, CB radio, and other low-frequency applications.
- LMR-240 Optimized: Precisely matched to the physical requirements of LMR-240 coaxial cable, ensuring a robust mechanical connection and the best possible performance up to its maximum frequency.
- EZ-Fit™ Solderless Technology: Features a cutting-edge spring-finger inner contact that eliminates the need for soldering the center pin, significantly reducing installation time and minimizing field errors associated with heat or poor solder joints.
- High Performance at Low Frequencies: Engineered for reliable 50 Ohm impedance matching up to 2.45 GHz (ideal for low-frequency applications where UHF is most common).
- No Braid Trim Design: Simplifies cable preparation by eliminating the braid trim step, ensuring a consistent, optimal termination geometry and reducing Foreign Object Debris (FOD).
