The C90-3106F10SL-4P is a straight plug circular connector designed for high-reliability applications requiring MIL-DTL-5015 (MIL-C-5015) compliance. It features a 10SL shell size with 5/8-24UNEF thread, 2 male contacts, and solder termination with a back shell for environmental sealing. The connector is rated for 13 A current, 500 V AC / 700 V DC voltage, and 2,000 V AC dielectric proof, with insulation resistance of 5,000 MO minimum. It operates across -55 °C to +125 °C, withstands vibration up to 10 Hz–500 Hz at 98 m/s² (10 g) and shock of 490 m/s² (50 g) for 11 ms, and exceeds IP-67 sealing when used with back shells and gaskets. This connector is ideal for harsh industrial, aerospace, and marine environments where ruggedness, durability (500 cycles minimum), and environmental protection are critical.
