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, robotics and industrial automation requiring RF links,smart meters and remote monitoring devices 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.

What’s the difference between male and female RF connectors?
Male: Has a center pin and usually an outer thread or bayonet. Female: Has a receptacle (socket) for the center pin and matching thread. Some connectors (like SMA) can be confusing because “reverse polarity” (RP-SMA) swaps pin/socket configuration.
What is VSWR, and why does it matter?
VSWR (Voltage Standing Wave Ratio) indicates signal reflection. Ideal: 1.0 (perfect match). Lower VSWR means less signal loss and distortion.
What are typical applications of RF connectors?
Telecom (5G, LTE, satellite) Aerospace & defense (radar, avionics, secure comms) Test & measurement (network/spectrum analyzers) Broadcast & video distribution Automotive radar and IoT devices Medical imaging & equipment
What is the difference between RF connectors and coaxial connectors?
They are often used interchangeably. However: Coaxial connector refers to the physical design (shielded cylindrical form). RF connector emphasizes its use in radio-frequency applications. Most RF connectors are coaxial.
