Rectangular Connectors - Housings

0348408020 rectangular connectors are part of the range of housings from TE Connectivity, designed for use in both benign and harsh environments. The 0348408020 series makes use of low-profile contacts and shrouds to maximize density within the limited space available. With a range of sizes and different orientations, these connectors are highly versatile and suitable for a variety of applications.

Application Field

The 0348408020 series’ versatility make it suitable for a variety of markets, including industrial, communications, consumer electronics, and automotive. It is most commonly used in data acquisition, military, and aerospace. Data acquisition uses include Serial Peripheral Interface (SPI), Ethernet, and High-Speed Inter-Integrated Circuit (HSI). It is also useful in harsh environments including outdoors, docks, and military applications where robust connections are required.

Working Principle

The 0348408020 series consists of a housing, a central core, and two distinct sets of contact positions. The housing is a dielectric material with a lid that is designed to latch in place and provide a sealed environment for the contacts. The housing defines the length and orientation of the carriage and the core provides more precise positional control. The two sets of contact points are either male or female and they are designed to mate precisely with each other to ensure a dependable connection.

The contact interface is made up of an upper locking mechanism with a substrate on top. This substrate, also known as the “capacitor gate”, is equipped with integrated passives such as resistive elements and ceramic capacitors. This substrate contains a conductive path that is able to carry an array of signals and low-level voltages. Once the two halves of the connector are mated, the passives interact with each other in order to ensure a stable voltage or data flow between the two devices.

Conclusion

The 0348408020 series of rectangular connectors is a versatile design that is suitable for different industrial, communications, consumer electronics, and automotive applications. Its design allows for easy mounting in complex and crowded systems, while its low-profile contacts and shrouds maximize density and reduce assembly time. Furthermore, the core and contact positions provide more precise positional control and the integrated passives create a stable voltage and data flow between the two devices.
