The ITT CANNON MS3106R20-19PW connector is a heavy-duty, circular connector manufactured to MIL-DTL-5015 standards. Originally designed for aerospace applications, it's now widely used in commercial and military settings requiring extreme environmental reliability. Features include a wide operating temperature range (-55°C to +125°C), a robust aluminum alloy shell, and a resilient polychloroprene insulator. It's suitable for applications such as power generators, engines, sensors, and off-road vehicles, providing a secure and reliable connection in demanding conditions. The connector's threaded coupling provides superior EMI/RFI shielding and is easily assembled, reducing overall cost of ownership.
