With a durable design and superior contact retention, the D38999/20MJ11PN is widely used for a variety of applications in airborne, ground and shipboard environments. Currently there are 3 sizes of the D38999/20MJ11PN and each size is available in 1 to 11 position arrangements.

Applications

The D38999/20MJ11PN is suitable for a number of different applications, such as in military electronic systems, aircraft, medical systems, test and measurement instruments, data and communication systems, ground systems, industrial automation, and more. It’s also suitable for applications where the environment has high levels of vibration, shock, or extreme temperatures, since it’s designed to be rugged and reliable even in these conditions. It’s also resistant to EMI and RFI, making it highly reliable.

Working Principle

The D38999/20MJ11PN connectors are specifically designed for snap-in mounting on a panel or other equipment. The robust design of the connectors ensures that they can be mated and de-mated easily, with superior contact retention guaranteeing reliable performance even in tough conditions. The connectors feature 50 ohm rectangular contacts rated at 20amps each, capable of carrying signal, power, and ground connections. The contacts are formed into strips within the connector shell, and are inserted into the female contact pocket when the plugs are mated. The D38999/20MJ11PN also comes with backshells for EMI and RFI shielding, and for strain relief, further ensuring that the connection is secure and reliable.

The contact surface of the D38999/20MJ11PN is gold-plated, which helps to reduce electrical resistance and improve signal integrity. The silver-plated shells are also environmentally sealed, providing more reliable protection from any moisture or contaminants that could damage the internal connections. In addition, the high-temperature insulators help to ensure that the connector remains resistant to heat, allowing it to work in applications where extreme temperatures are present.

The D38999/20MJ11PN is designed to be a durable, reliable connector system that can help a wide variety of applications. The snap-mounting design and robust construction ensure that the connector will be secure and reliable in even the most harsh conditions. The gold-plated contact surfaces and environmental sealing further enhance its performance, ensuring that it can be relied upon in even the toughest of environments.
