BNC connector have a two stud bayonet locking design, and has same interface with TNC connector. BNC connector supports with a large variety of coaxial cables like RG58, RG174, RG316, RG59.
50 ohm BNC connector was commonly used on 10base2 thin Ethernet networks, and now is used in radio and telecommunication.
75 ohm BNC connector is available for CATV, CCTV applications and is successfully work up to 1GHz.
Mechanical Feature:
BNC male
•A rotated coupling nut with two locking caves symmetrically.
•Male center contact
•Silicon Rubber O-ring inside between coupling nut and outer contact
•Insulator nestles up throughout against outer contact, and an air gap between center contact and insulator for 50 ohm BNC male
•Reduced insulator in mating end, and an air gap between center and outer contacts for 75ohm BNC male
BNC female
•Two symmetrical studs for lock mating.
•Female center contact
•Insulator surrounds female center contact wholly for 50 ohm BNC female
•Part of female center contact doesn’t be surrounded by insulator and an air gap between center contact and outer contact for 75 ohm BNC female
