Description
The Mini BNC male crimp connector is a specialized RF component designed to provide a secure and efficient connection in environments where space is at a premium. While it retains the quick-connect bayonet locking functionality of a standard BNC, the Mini BNC (M-BNC) interface is significantly smaller, enabling higher port density on equipment panels. This variant is optimized for the 2.5mm to 3mm cable class, specifically calibrated for the dimensions of high-performance thin-diameter cables including LMR100, RG174, and RG316.
As a male interface (plug), it features the classic two-stud bayonet locking system for rapid, vibration-resistant mating. This connector utilizes a hex-crimp termination system for the outer conductor, providing a high-strength mechanical bond and superior strain relief for flexible, small-diameter cabling. Manufactured with a durable nickel-plated brass body and premium PTFE (Teflon) insulation, it ensures low signal loss and consistent performance across a wide range of frequencies, making it ideal for precision instrumentation and mobile communication systems.
Key Technical Advantages
-
High-Density Footprint: The reduced size of the Mini BNC interface allows for significantly increased connector density compared to standard BNC connectors, perfect for compact enclosures.
-
