How to test the quality of bnc interface? The two methods can be simply compared

The BNC connector (English: BayonetNeill-Concelman, literally translated as "Neil-Concelman bayonet") is a very common RF terminal coaxial cable terminator. Used for the transmission of radio frequency signals, including the transmission of analog or digital video signals, the connection of amateur radio equipment, avionics equipment and some other electronic test equipment. TXGA specializes in various types of high-quality BNC connectors for fifteen years. It is our pursuit to provide you with more suitable products. Click [Product Center] and immediately buy a BNC connector.

The BNC connector has not been replaced so far, because the coaxial cable is a shielded cable, which has the advantages of long transmission distance and stable signal. At present, it is also widely used in communication systems. For example, the E1 interface in network equipment is connected by two coaxial cables with BNC connectors. It is also often used to transmit audio and video in high-end monitors and audio equipment. signal..

The BNC interface can isolate the video input signal, so that the interference between the signals is reduced, and the signal bandwidth is larger than the ordinary 15-pin D-type interface, which can achieve better signal response.

So when using BNC interface, how to distinguish the quality of BNC?

First, the magnetite adsorption test: under normal circumstances, only the bayonet spring and tail spring are made of iron; the clip and pin are made of copper, and the other parts are made of zinc alloy;

Second, scrape the surface coating to see the material: scrape the coating of the surface through the dao chip and other sharp tools to visually see the material, and visually compare the product material by scraping the clip, pin, and shield sleeve coating;

TXGA has been focusing on the production, development and sales of connectors for fifteen years. It has accumulated rich technical experience and has a good reputation in the national connector market.
