The 034-1126-12G is a 12G HD-SDI capable BNC straight-through connector designed for PCB mount in broadcast video equipment. It features a gold-plated brass body, gold-plated beryllium copper SMT contact, and a nickel-plated brass nut with a PTFE insulator. This connector supports 12G-SDI signals for 4K Ultra HD applications, offering a frequency range from DC to 18GHz with excellent return loss. It is true 75 ohm impedance, with a dielectric withstand voltage of at least 1000Vrms, and supports a minimum of 500 mating cycles. The connector is suitable for use in mobile broadcast systems, patch panels, HD cameras, digital signage, video encoders, and remote viewing applications. It is designed with a familiar BNC bayonet coupling mechanism and optimized for high-quality, reliable signal transmission.
