The connector features a nickel-plated body with gold-plated crimp contacts, designed for cable group C1 applications. It is rated for industrial-grade use and supports frequencies up to 11 GHz with typically low reflection through 4 GHz. The bayonet quick-connect design enables mating with only a quarter turn of the coupling nut, making it ideal for rapid cable termination in RF and signal applications requiring reliable, repeatable connections.
