The CA18220-10 is a circular connector from the CA Bayonet series, featuring a 3-contact arrangement (18-20) designed for reliable performance in harsh environments. It is equipped with three size 16 contacts, holds a service rating of 'A', and offers multiple insulator polarization positions (0°, 90°, 180°, 270°) to prevent mismating. The connector's rugged aluminum alloy shell and reverse bayonet coupling provide exceptional vibration resistance (200 m/s² at 10-2000 Hz) and allow for over 500 mating cycles. It ensures environmental protection with sealing rated to IP68 and IP69k and operates within a temperature range of -55°C to 125°C. These features make the CA18220-10 highly suitable for demanding applications such as off-road vehicles, industrial machinery, railroad equipment, and military hardware.
