The ITT CANNON MS3106F18-4SF187 connector is a robust, circular connector manufactured to MIL-DTL-5015 standards. Originally designed for aerospace applications, it's now widely used in commercial 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 in power generators, engines, sensors, and off-road vehicles. The threaded coupling provides superior EMI/RFI shielding.
