Ruggedized SMA connectors serve harsh environments

AMPHENOL Rugged Connector (ARC) series now includes SMA devices specifically designed to boost performance in harsh conditions, making them suitable for outdoor applications where extreme weather conditions may be a consideration. Interconnect solutions are rated IP67 in both the mated and unmated condition. Equipped with reliable threaded interface, devices are constructed using nickel plating over brass to provide robust performance in less than optimal environments. The 50 ohm interconnects are available in straight and right angle configurations and operates with minimal reflection for the full range of the cable, dc to 8GHz.
