D38999/20FE99SD is a waterproof electrical connector that meets the requirements of the MIL-DTL-38999 standard, providingadded performance, reliability, and affordability. It is typically used in demanding aerospace and defense applications such as interconnection of avionics systems. This type of connector is often preferred in specialized applications, due to its superior performance against moisture, vibration, electromagnetic interference, and shock. In addition, the connector has a unique pinout and latching system, which makes it the ideal solution for quick and easy disconnection and reconnection of electrical and data connections.

This connector features a two-piece construction, with two identical shells that are mated together perpendicularly. Each shell contains contact cavities for up to 20 contact pins, with the option of inserting up to 6 thermocouples. The D38999/20FE99SD also features a threaded locking ring and optional security screw, which further improves rigidity and resistance against vibration and shock. Due to its superior performance and robust features, this type of connector is most commonly used in aerospace applications such as aircraft interconnects, navigation systems, instrumentation, and avionics systems.

The working principle of the D38999/20FE99SD connector is based on the electrical contact design, which ensures reliable and secure electrical connections when engaged. This type of contact design is primarily determined by the contact volume, putting pressure on the contact surfaces to reduce the contact resistance and increase electrical contact stability. For example, a thin wall contact with a material cross-section greater than that of a standard type contact will offer increased performance and durability in difficult environmental conditions.

In addition, the D38999/20FE99SD connector is designed with an electrical contact that is rotatable and balanced, allowing it to maintain reliable electrical connections in high-vibration environments. This feature also enhances the connector\'s ability to resist moisture, dust, and corrosion. The pins and sockets of the connector are also machined to precise tolerance, ensuring tight tolerances and consistent electrical connections. The optional thermocouple insert further improves performance and ensures reliable temperature measurement and control.

The D38999/20FE99SD connector is a rugged, reliable, and cost-effective solution for demanding aerospace and defense applications. Its superior design, performance, and features make it the preferred choice for quick and secure connection of avionics and other sensitive electronic components. The contact design of the connector ensures reliable electrical connections when engaged and its ability to resist moisture, dust, and vibration makes it the ideal solution for hostile and harsh environment applications.
