The 165-61X-1028 is a miniaturized square flange receptacle connector from the Amphenol 165 Series, designed for applications requiring a lightweight, MIL-C-5015 compliant interconnect. This connector is configured with eight #20 socket contacts and one shielded contact, with a current rating of 10.0A and a voltage rating of 500V RMS at sea level. It features a quick, positive bayonet coupling mechanism and O-ring seals to ensure it is pressure-proof and water-protected when mated. The shell is made of high-grade aluminum with a gray anodize finish, and the inserts are diallyl phthalate for high insulation resistance, making it ideal for demanding environments where size and weight are critical.
