Circular connectors are electrical connectors used in a variety of applications, including military, aerospace, industrial, automotive, and medical equipment. Backshells and cable clamps are essential components of a circular connector, providing strain relief and connector protection against mechanical, environmental and electrical/electromagnetic interference. H/MS3057-4A is a circular connector with backshells and cable clamps designed for military and aerospace applications.

The H/MS3057-4A is designed for use in harsh environments, meeting criteria of MIL-DTL-38999, Series IV and compliant with MIL-DTL-38999. It is created for applications that require additional sealing between the connector and backshell, such as pressurized environment, and offers superior shielding effectiveness with intricate contact geometries and improved shielding capability of the dielectric material. The backshells are made of high grade heat treated aluminium and are available in straight and right angle configurations. The cable clamps are constructed of stainless steel for military environmental protection, with a choice of one to four clamps.

The H/MS3057-4A utilizes a secure push and turn lock mechanism to keep the male and female contacts in place. The contacts are solder-type for ease of assembly and removal, with gold or silver plated contact pins depending on customer requirements. The connector is available with a variety of standard insert arrangements, including three, four, five, six, seven, nine, and fifteen contacts in a variety of pin sizes, with maximum current rating of 47.5A depending on the contact size.

The overall performance of the H/MS3057-4A connector is excellent picture, with excellent high frequency signal transmission and flexural strength that exceeds MIL-DTL-38999 requirements. The connectors are designed to be vibration-resistant and immersion-resistant up to 1m for 30 minutes. They also have fire retardant and nonmagnetic properties. Heat shrink tubing and additional sealing can be added for additional environmental protection and sealing.

The application field of the H/MS3057-4A connector includes military and aerospace applications such as guided weapons, aircraft, ships, UAVs, helicopter avionics, radar systems, navigation equipment, computers, EW systems, analysis systems, intranets, satellite ground station communication, communications stations, navigation/radar systems, and more. The connector is also suitable for outside use in areas where water and dust resistance and EMI protection are necessary.

In conclusion, the H/MS3057-4A connector is an extremely reliable and rugged connector designed for military and aerospace applications. The backshells and cable clamps provide excellent protection and strain relief, and the secure locking mechanism ensures reliable and stable connection. It is able to withstand a wide range of environmental conditions, making it suitable for both indoor and outdoor applications.
