The BNC Male Connector Cable Assembly with RG58 Cable represents an industry-standard solution for reliable, medium-frequency radio frequency (RF) and video signal transmission. Combining the quick-connect BNC (Bayonet Neill–Concelman) Male connector with the highly versatile and widely adopted RG58 coaxial cable, this assembly delivers a dependable, 50-ohm impedance path suitable for a vast array of general-purpose electronic and communication applications.
Key Product Features and Technical Specifications
Engineered for performance, ease of use, and durability, our BNC Male/RG58 assemblies offer a balanced solution for professional and enthusiast use alike.
BNC Male Connector Reliability and Speed
The BNC Male connector is distinguished by its bayonet coupling mechanism, a quarter-turn feature that allows for quick connection and disconnection. This is a significant advantage in environments where frequent cable changes are required, such as test laboratories and mobile broadcast setups. The bayonet lock ensures a secure, positive engagement that minimizes the risk of accidental disconnection due to vibration or tugging.
Our BNC Male connectors are typically precision-machined from brass and plated with nickel, providing excellent corrosion resistance and mechanical strength. The center pin is gold-plated to guarantee minimal contact resistance, which is vital for maintaining low insertion loss and a favorable Voltage Standing Wave Ratio (VSWR). The connector is rated for reliable electrical performance up to approximately 4GHz, covering a wide range of common wireless and instrumentation frequencies.
The Versatility and Robustness of RG58 Cable
The RG58 coaxial cable is one of the most popular coaxial cables globally, prized for its excellent balance of size, flexibility, and electrical performance. It features a nominal 50-ohm impedance, making it the standard choice for most RF communications.
Key characteristics of the RG58 cable include:
Conductor: Stranded copper conductor, offering excellent flexibility and durability against repeated bending and flexing, unlike solid conductors.
Dielectric: Polyethylene (PE) dielectric, providing a stable impedance and good propagation velocity.
Jacket: Typically a flexible PVC (Polyvinyl Chloride) jacket, offering good protection against abrasion and moisture in standard operating environments.
Shielding: Braided copper shielding, providing effective protection against electromagnetic interference (EMI) and radio frequency interference (RFI), crucial for maintaining signal integrity in noisy environments.
Its moderate size makes it easy to route and handle, and while it exhibits slightly higher attenuation (signal loss) than larger diameter cables like RG8, its flexibility and cost-effectiveness make it the superior choice for shorter runs ) in numerous applications.
Quality Assembly and Low Loss Performance
Each cable assembly is professionally terminated to ensure optimal electrical and mechanical integrity. We use high-quality crimping tools and soldering techniques (where necessary) to ensure the BNC connector is permanently and securely affixed to the RG58 cable. The termination process is controlled to preserve the cable's 50-ohm impedance, resulting in a low VSWR across the operating frequency band. This meticulous assembly process translates directly to reliable signal transmission, minimal signal reflection, and maximum power efficiency for connected devices.
Practical Applications and Usage Scenarios
The combination of the secure BNC connection and the flexible RG58 cable makes these assemblies an essential component in a multitude of industrial, professional, and commercial settings.
Test and Measurement Laboratories
The BNC interface remains the dominant connector for connecting signals on equipment like oscilloscopes, function generators, frequency counters, and signal analyzers. BNC Male/RG58 assemblies are used universally as durable, flexible patch cords for coupling signals between various components on a workbench. The quick bayonet action is ideal for the rapid connection changes common in R&D and quality assurance labs.
Amateur Radio and Low-Power Communications
In amateur (Ham) radio and other low-power communications systems, these cables are frequently used for connecting transceivers, antenna tuners, and test gear. The $\text{50-ohm}$ impedance of the RG58 is standard for these applications, and the flexibility allows for easy station setup and movement.
Legacy Computer Networking (Ethernet)
Although largely superseded, the BNC Male/RG58 assembly was the foundation of the original Thin Ethernet (10BASE2) computer networking standard. While not used in modern Ethernet, these cables are still essential for maintaining and servicing legacy networking equipment in specialized industrial, military, or historical installations.
Instrumentation and Industrial Monitoring
In industrial environments, the assemblies are used to connect transducers, sensors, and data acquisition units to control systems. Applications include vibration monitoring, machine diagnostics, and various forms of industrial process control where reliable signal routing over short distances is required.
