Rectangular Connectors - Headers, Receptacles, Female Sockets

Rectangular connectors are important components of electronic circuits and have been around as a commercial component type for decades. 150254-5122-RB specifically is a housing style used for electronic devices with a three-pin female plug. This kind of rectangular connector is commonly referred to as a header, receptacle, or female socket. It’s made up of an insulated plastic housing and three metal connector pins - two pins on the right side and a ground on the left.

Application Field

The main application field for rectangular connectors - headers, receptacles, and female sockets all together - is in the manufacture and assembly of electronic equipment, appliances, and products. The typical use for 150254-5122-RB connectors is in a variety of electronic products where two or more female connections need to be connected. These connectors are typically used in applications such as PCBs, DC power supplies, as well as other communication, automotive, and audio/video equipment.

Working Principle

The rectangular connectors are easy to use and their simple design makes them reliable. The first step is to accommodate the connector’s two right-side pins into the female connector housing - typically a female mini-molex connector. Then the ground pin is connected via a plated copper wire to the exposed conductive surface of the housing or the PCB. The connection is then secured by soldering both the two pins to the appropriate contacts on the PCB. The device is then tested and verified for proper operation.

Rectangular connectors like 150254-5122-RB offer reliable contacts with a low thermal resistance value, making them perfect for current-load carrying applications. This value makes them extremely suitable for safety-critical and high-quality applications like datacom, audio/video equipment, security systems, etc. In addition, they have a low-profile design and are space-saving, making them perfect for tight spaces and electronic enclosures.

Conclusion

Overall, 150254-5122-RB and other rectangular connectors are essential components for use in the assembly of electronic equipment, appliances, and products. They provide a reliable and safe connection, and are suitable for both current-load and safety-critical applications. These connectors, though known for their simplicity, offer a crucial element to many devices.
