Durable QMA Male RF Connector Straight Crimping Brass Body Nickel Plated For RG8, LMR400 Coaxial Cable

The QMA connector is a quick-connect / push-on style RF coaxial connector, designed as a “snap-on locking” alternative to the standard threaded SMA connector.
he design was developed by the Quick Lock Formula (QLF) Alliance (comprising companies like Amphenol RF, Radiall, Rosenberger Hochfrequenztechnik and Huber+Suhner) around 2003

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.
