Rectangular Connectors - Headers, Receptacles, Female Sockets are components often used to connect circuits electrically and to provide mechanical support. The 68402-202LF type of Rectangular Connectors is a 2mm pitch SMT header and has a variety of applications. This article discusses the basics of the connectors, fields of application and working principle.

Overview

The 68402-202LF Rectangular Connectors has two row of 2mm Bladed Pins with 20 pins each. The header being surface mounted is widely used when space is limited in the product. It is a cost effective option, easy to use and maintain. Depending on the requirement of the application material for housing and contact can be chosen, such as Phosphor Bronze or BeCu alloy for contacts. It has solder tails for attaching onto the container, strain reliefs or anti-vibration protection.

Applications

The United States Department of Defense (US DoD) uses similar rectangular connectors in tactical and military applications for communication and data transmission. These applications generally involve hazardous environment conditions, such as extremely high and/or low temperatures, vibration, pressure, and so on. By design, the connectors must remain secure while containing harsh environmental conditions.

Apart from being used in military and aviation applications, there are numerous other uses of rectangular connectors. They are commonly used in various communication systems. These include cellular, radio, satellite and wireless applications. These connectors are also widely used in commercial aviation for connecting computers used for navigation, control panels, communication and entertainment systems.

In addition, the 68402-202LF type of rectangular connectors are primarily deployed in single-board computers (SBCs) for embedding a chip, enabling the SBC to function as a single board computer. These connectors are also used in communication equipment, as well as in consumer electronics, industrial machinery, vehicle, instrumentation and security systems.

Working Principle

Rectangular connectors generally use either pin or socket type contacts and act like switches. They are designed to allow electrical current or signals to flow between two or more devices. The pins are embedded in the connector body or are inserted into or out of the connector. The two rows of pins are connected to the respective contacts using simple soldering techniques. When the connection is established, the pins will make contact with the teech in the connector, providing an electrical path for the current or signals to flow across both devices.

The advantage of rectangular connectors is that they are easy to assemble, providing an efficient and reliable method for electrical wiring of devices. The connector types can also be customized according to the application requirements. The parts of the connector can be assembled quickly without needing specialized tools or techniques. Moreover, these connectors are relatively robust and designed to withstand harsh environments.

Conclusion

The 68402-202LF rectangular connectors are widely deployed in all sorts of applications, including military and aviation, communication systems, SBCs, consumer electronics, and industrial machinery. The connectors provide an efficient and reliable way for electrical wiring of devices. They are also resistant to harsh environmental conditions and can be customized for different applications. All in all, these connectors are an excellent option when device connectivity is needed.
