BNC Connectors

 
Description :
Bestnet BNC series connectors are general-purpose, low-cost miniature connectors, with a frequency range of DC–4 GHz and 50 Ω impedance, designed to MIL-PRF-39012 requirements. Their bayonet-type interface provides quick mating and unmating, and prevents accidental disconnection from pulling forces on the cable. Automatic BNC cable connectors are available with nine standard cable attachment types for flexible and semi-rigid cable:
