ITT CANNON MS3108R12S3SW Heavy Duty Connector

The ITT CANNON MS3108R12S-3SW connector is a robust, circular connector manufactured to MIL-DTL-5015 standards. Originally designed for aerospace applications, it's now widely used in industrial and military settings requiring high reliability in harsh conditions. Features include a wide operating temperature range (-55°C to +125°C), a variety of contact options (solder, crimp, PC, thermocouple), and a rugged aluminum alloy shell. Its sealed design provides excellent protection against vibration, water, and condensation, making it suitable for applications such as power generators, engines, and off-road vehicles. The threaded coupling provides superior EMI/RFI shielding.
