The center contact is soldered (solder termination), and the shield is secured with a clamp — a field-reliable method that avoids the need for a crimp tool. The silver-plated brass center contact and nickel-plated brass body provide good conductivity and corrosion resistance for indoor and sheltered outdoor use. The 500 V rating is typical for BNC interfaces and covers most RF and low-power applications. The 31-206 includes a lockwasher and nut for panel mounting, whereas the 31-202 comes with a gasket and washer for cable-end assembly. Choose the 31-202 when you need a male plug on the cable end; choose the 31-206 for a panel-mount receptacle.","metaTitle":"Amphenol 31-202 BNC Plug, 50 Ohm, 4 GHz, Silver Contact","metaDescription":"Amphenol 31-202 BNC plug, male pin, 50 Ohm, 4 GHz, 0.2 dB loss, 500 V.
