Description
QMA Plug (Male) | Soldered Cable Entry | Quick Lock | Brass Body
The ROSNOL QMA1E50-0141A/144 is a QMA plug (male) connector designed for 50 Ω RF applications operating up to 6 GHz. Featuring a quick-lock coupling mechanism, this connector enables fast and secure mating while maintaining stable electrical performance. The soldered cable entry with a soldered center contact ensures reliable cable termination and consistent impedance control. With a VSWR of ≤ 1.15 and low insertion loss characteristics, this connector supports dependable RF signal transmission in compact and high-density installations.The connector body and coupling nut are manufactured from brass with a copper–tin–zinc alloy composition to provide mechanical strength and durability. The center contact is produced from brass with gold plating over a non-magnetic nickel-phosphorus underplating to ensure low contact resistance and long-term electrical reliability. A PTFE insulator maintains stable dielectric performance. The QMA1E50-0141A/144 is compatible with .141 cables including RG402, ROSNOL RSR-141, RSF-141, and EF402.
ROSNOL’s precision-engineered RF connectors offer a competitive alternative to products from leading manufacturers in Europe, the USA, and other global markets. All Rosnol RF components are precision-manufactured in ISO 9001-certified facilities and are fully RoHS and REACH compliant. Customization services for materials, plating, and mechanical design are available upon request.
