Rectangular connectors have been widely used in many industrial applications for decades, and continue to be an integral portion of current designs. The PPPC121LFBN head receptacle is one type of these connectors that features a rugged yet reliable design and is able to withstand numerous harsh environments. Here, we will discuss their application field and working principle.

PPPC121LFBN Application Field and Working Principle

The PPPC121LFBN head receptacle is a rectangular connector with two rows and a total of 121 female pins. Designed with a high-temperature-resistant plastic, the PPPC121LFBN head receptacle is ideal for usage in lightly polluted areas and in extreme temperature applications. Its matrimonial component, the PPPC121LFBN male header, comes in a two-row version and has a size of 3.00mm pitch x 0.50mm pin diameter. This type of rectangular connector is suitable for applications ranging from automotive, instrumentation and industrial controls to commercial and domestic appliances, automation and robotics.

The PPPC121LFBN head receptacle’s operating principle can be seen as a mechanical connection between the external units that provides an electrical path from one external unit to the other. The two rectangular connectors are inserted into each other when their polarized features are aligned, and afterwards a mechanical link is created that also provides an electrical connection. The female socket’s pins are soldered in the printed circuit board and the male header’s pins reach into the female socket’s horizontal slots. The application of an axial load is needed to ensure a positive sealed contact between the pins and the slots.

In addition, the PPPC121LFBN head receptacle is designed to quickly and easily install and long-term reliable operation. It features fast and easy PCB mounting through its kink screw holes which guarantee secure mounting while preventing any drift of the receptacle from its original position. In addition, the connector’s secure connection and disengaging mechanisms make the PPPC121LFBN ideally suited for disconnect-type applications.

Conclusion

The PPPC121LFBN head receptacle is a male-female rectangular connector with 131 pins for use in a variety of industrial, commercial, and domestic applications. The main feature of such connector is that it provides an electrical path between the external units while at the same time ensuring a secure mechanical connection. Its features have also been designed to offer easy PCB mounting, fast and easy installation, and long-term reliable operation.
