Low Loss QMA Male RF Connector Straight Crimping Brass Body Nickel Plated For RG316 RG174 Coaxial Cable

The QMA connector is a quick-lock 50 Ohm RF coaxial interface designed as a faster, easier alternative to the traditional SMA connector. Featuring a snap-on coupling mechanism, QMA connectors allow tool-less installation and 360° rotation after mating, providing exceptional flexibility for cable routing and dense RF module layouts. With similar internal dimensions and electrical performance to SMA, the QMA ensures low VSWR, excellent shielding effectiveness, and stable signal transmission up to 18 GHz. The compact design eliminates the need for wrench clearance, enabling higher connector density and faster assembly in field or production environments. Typical applications include base stations, antennas, wireless modules, test systems, and industrial communication equipment where quick, reliable RF connections are required.

FAQ

Sample Delivery Time

Regular models require 15 days, while some complex connectors require 25 days.


Sample Fee

Most RF connectors are CNC-machined parts and do not require mold-making.

However, each part needs to be fine-tuned on the CNC machine. Typically, a single sample costs $200.

This fee will be refunded after a 5K bulk order.


Guarantee


Brass RF connectors come with a one-year warranty.

Stainless steel connectors come with a three-year warranty.

The lifespan also depends on the contact material—beryllium contacts offer better durability.


ROHS & REACH Compliance

Our products fully comply with ROHS & REACH regulations.

Does LENORF Offer Military-Grade Products?

Yes. We are honored to provide military-grade products with exceptionally stable quality.

What’s the lifespan of an RF connector?

Connector durability is rated in mating cycles: General-purpose connectors (BNC, SMA): 500 cycles. Precision connectors (2.92 mm, 2.4 mm): 500 cycles or less. Rugged telecom connectors (N, 7/16 DIN): 500 cycles.


Can RF connectors be reused?

Yes, but performance degrades with wear. Precision connectors (used in test equipment) should be handled carefully—damage to threads or pins increases VSWR and insertion loss.
