RQ Receptacle Connectors

Winchester Interconnect Micro, formerly known as Ulti-Mate Connector, offers our RQ Receptacle Connectors. They offer a versatile and high quality solution for various applications, available in both front and rear panel mount configurations. These circular connectors provide ease of coupling, a round cable bundle form, and easy panel mounting. The connectors feature a low contact resistance of 8 milliohm max for contact-only connections and 32 milliohms max with 6" wire at 2.5A. They have a current rating of 3A max and a dielectric withstand voltage of 600 VAC at sea level and 150 VAC at 70,000 feet, along with a maximum 1mA leakage current.
