The 034-1122-12G is a 75 ohm HD BNC right-angle plug connector designed for use with Belden 4855R cable and provides IP-67 sealing when mated. It features a frequency range of DC to 18 GHz with return loss of -20 dB from DC to 6 GHz and -15 dB from 6 to 12 GHz, making it suitable for high-frequency RF applications. The connector is constructed with brass nickel-plated rear body and bayonet sleeve, BeCu nickel-plated outer contact, phosphor bronze gold-plated contact, copper nickel-plated ferrule, and PTFE natural insulators, with a stainless steel passivated cap. It operates reliably across a temperature range of -65°C to +165°C and offers a minimum durability of 500 mating cycles, meeting MIL-STD-202 standards for thermal shock, vibration, shock, and corrosion resistance. This connector is ideal for demanding RF and microwave applications requiring high-density installations, reliable sealing, and consistent impedance performance.
