Overview
The BNC connector is a miniature, quick-connect RF coaxial connector widely used for analog and digital signal applications. It features a bayonet-style coupling mechanism that allows secure, reliable connections with a simple twist-and-lock action. BNC connectors are typically available in 50ohm and 75ohm impedance versions, supporting frequencies up to several GHz depending on the design. They are commonly used in test equipment, broadcast systems, video applications, instrumentation, towers, repeaters, routers, and access points for reliable RF signal transfer,5G, LTE, Wi-Fi, and satellite communication systems and networking. BNC connectors are valued for their durability, ease of use, and consistent electrical performance. Both straight and right-angle versions, as well as PCB-mount options, are available to accommodate diverse layouts.

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.

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.
What’s the difference between threaded, bayonet, and push-on RF connectors?
Threaded (SMA, N, TNC): Secure, vibration-resistant. Bayonet (BNC): Quick connect/disconnect. Push-on (MCX, SMP): Ultra-fast, compact, used in high-density modules.
Are RF connectors interchangeable between brands?
Yes, if they follow the same standard (e.g., SMA-to-SMA). However, tolerances, plating, and dielectric quality vary — mixing low-quality and precision connectors can damage equipment.
How do environmental conditions affect RF connectors?
Temperature extremes can cause expansion/shrinkage and change performance. Humidity and salt spray may cause corrosion (use stainless steel or weatherproof designs). Vibration may loosen bayonet types — use threaded connectors in harsh environments.
