Think big electronic (STA) Division - Professional focus on providing RF coaxial connectors and antennas: BNC is a very common RF terminal coaxial cable terminator. BNC connector that is often said thin coaxial interface. BNC interface can be isolated from the video input signal, so that mutual interference between signals decreases, and the signal bandwidth than the average 15-pin D-type large interface can achieve better signal response effect. [1] Category Application category: BNC tap wire type, board type, transfer type and connection type connection type is mainly used to monitor the main points :( wiring construction project) cold type, such as: BNC-JC et Q9 categories, such as : BNC-JS, etc. Among these points welded and free welded extruded plastic circuit board assembly-pressing principal points :( mainly used in electronic engineering equipment, connecting terminal exit or entrance) nut category, such as: BNC -50 / 75KY JY et screwing categories, such as: BNC-50 / 75KF JF other welding class, such as: BNC-KE BNC-KWE BNC-JE wide range of adapter class: almost all can achieve the conversion between the connector Other categories include: two-way connection, terminal plugs and other materials classification: can be divided into brass, zinc alloy, stainless steel BNC connectors General characteristics: Technical characteristics: Characteristic Impedance: 50Ω / 75Ω Frequency range: 0 ~ 2GHz Contact resistance : inner conductor ≤2.0mΩ; external resistor ≤0.2mΩ Insulation resistance: ≥5000MΩ Dielectric strength: 1500V VSWR: ≤1.3 Connector Durability: 500 times, materials and coating: Center contacts: Pin - Gold-plated brass (bold); Jack - bronze or bronze, gold housing and other metal parts: brass, nickel (thicker) Insulation: PTFE (high temperature) clip: yellow copper, silver ring: silicone rubber usage BNC coaxial cable connector is a shielded cable, there is a long distance transmission, signal stability advantages. Now it has been widely used in communications systems, such as network equipment E1 interface is to use two BNC coaxial connectors to connect to, and in high-end monitors, audio equipment is also often used to transmit audio and video signals . Applications: WLAN, radio lead, RF (radio frequency) applications, low loss coaxial applications, Wi-Fi application, but also to monitor the project for the camera device output common connector.
