The 031-220N-75 is a 75O straight jack-jack bulkhead adapter manufactured by Amphenol RF, designed for RF signal interconnection in miniature coaxial cable applications. This connector features a nickel-plated body with gold-plated contacts, providing reliable electrical performance and corrosion resistance. The adapter is rated for industrial-grade applications and accommodates standard BNC jack connections on both ends. With its 75O impedance characteristic, it is well-suited for video and broadband signal transmission applications where impedance matching is critical. The bulkhead mounting configuration makes it ideal for panel-mount installations in test equipment, broadcast systems, and professional audio/video infrastructure.
