The 2435-87-16 is a keyed TNC plug connector manufactured by Winchester/Kings, designed for high-frequency RF and microwave applications requiring polarized mating. It features a 222° keying angle to ensure correct orientation and prevent incorrect connections. The connector is rated for 500 VRMS with a nominal impedance of 50 O and operates across a frequency range from DC to 11 GHz, making it suitable for broadband signal transmission. The connector is constructed with Teflon insulators, beryllium copper outer contacts, and phosphor bronze C-rings, with gold-plated center contacts and nickel-plated metal parts for enhanced durability and corrosion resistance. It is compatible with Boeing BMS13-65 OJ and Adams Russell FC3BZ cables and is commonly used in aerospace, defense, and telecommunications systems where reliable RF connections and keyed mating are critical.
