QMA Plug (Male) Right-Angle Cable Connector for .141, RG402, RSR-141, RSF-141, EF402, DC-6 GHz VSWR 1.15

QMA Plug (Male) | Soldered Cable Entry | Quick-lock | Brass Body

The ROSNOL QMA1E59-0141A/144 is a QMA Plug (Male) right-angle connector designed for reliable RF performance from DC to 6 GHz. With a 50 Ω impedance, VSWR ≤ 1.15, low insertion loss, and excellent RF leakage suppression, it supports stable signal transmission in compact microwave assemblies. The mechanical configuration features a quick-lock coupling mechanism for rapid mating, ≥ 100 mating cycles, axial center-contact captivation ≥ 20 N, and typical engagement/disengagement forces of 25 N and 20 N. The connector utilizes a soldered center pin and solder-type cable entry compatible with .141 and RG402‑class semi‑rigid cables.

Piece parts are engineered for durability and RF stability: the centre contact is gold‑plated brass with non‑magnetic nickel‑phosphorus underplating; the body and coupling nut are constructed from a brass copper–tin–zinc alloy; and the insulator is PTFE. Suitable cable types include .141, RG402, Rosnol RSR‑141, RSF‑141, and EF402. This connector is well‑suited for RF modules, densely routed microwave systems, and communication equipment requiring secure, low‑profile right‑angle QMA terminations.

ROSNOL’s RF components provide high performance at competitive pricing, serving as dependable alternatives to leading European and American brands. All ROSNOL connectors are manufactured in ISO 9001‑certified facilities and fully comply with RoHS and REACH requirements. Customization services for materials, plating, and mechanical configuration are available to support specialized RF and microwave design needs.
