Introduction to M85049/1921N03

The M85049/1921N03 is a circular connector backshell and cable clamp used in aerospace and defense applications. This backshell and clamp is specifically designed for MIL T connectors, making it an ideal choice for military aircraft wiring, radar systems, and other highly specialized applications. It is designed to be resistant to environmental conditions, including shock, vibration, moisture, fuel, and fungus, and meets strict military specifications. The backshell and cable clamp is made from lightweight and durable aluminum, and provides strain relief and twist suppression for 19 and 21-position MIL T connectors.

Types of M85049/1921N03

The M85049/1921N03 is available in several different configurations, including straight body, 90 degree elbow body, and 180 degree double elbow body. Each configuration provides a different cable routing option, depending on the specific needs of the application. The straight body is ideal for applications where the cable routing need to be kept tight and tucked closer to the connector while the 90 and 180 degree elbows give the option of larger turns and longer cable separation. The M85049/1921N03 can also be ordered with a color coating that provides additional environmental protection for the connector system, as well as an improved appearance.

M85049/1921N03 Application Fields

The M85049/1921N03 backshell and cable clamp is designed for use in a variety of aerospace and defense applications. In particular, the backshell and cable clamp is often used in aerial refueling, airborne fire suppression, and flight testing applications. It is also suitable for use in aircraft instrumentation wiring, antenna systems, radio frequency identification (RFID) systems, ground support equipment, communications equipment, and other specialized aerospace applications.

M85049/1921N03 Working Principle

The M85049/1921N03 backshell and cable clamp provides strain relief and twist suppression for MIL T connectors. It is designed to be used with MIL T connectors that have a 19 or 21-position termination. The backshell and clamp are designed to be installed after the wires have been pushed in to the cylindrical barrels of the connector body. Once the wires are in place, the backshell is tightened, which presses the cable clamp tight against the connector body, preventing movement of the wires and providing the necessary strain relief. The backshell and cable clamp also provides twist suppression, which prevents the wires from being twisted or disconnected due to vibration or cable movement.
