Description

This catalog covers the electronic component model MS3471W14-5SY, a medium-sized circular connector with environmentally resistant features. It is designed to operate at a recommended voltage of up to 1000 VAC (RMS) at sea level. The connector utilizes a quick positive coupling system with a 3-point bayonet coupling mechanism, ensuring visual confirmation of complete coupling. To prevent mismating, it employs a five key/keyway design. Contacts can be easily inserted and removed from the rear of the connector without causing damage to the front sealing characteristics. The contacts are qualified to MIL-C-39029 requirements and are crimped using standard crimp tools per MIL-C-22520. The grommets used in this connector are constructed of tear-resistant elastomer and are not affected by exposure to a broad range of fluids. Sealing over a range of wire diameters is assured by a triple webbed grommet at the rear of the connector. The closed entry socket side of the insert is designed with a lead-in chamfer and a hard face that accepts a pin contact bent within pre-established limits. The pin side of the connector features an elastomer interfacial seal with raised barriers that displace into the socket chamfer when mated, providing a positive moisture seal.
