Introduction

The FX4B3-68P-1.27SV (71) is an edge-type array connector, a type of rectangular connector. Generally, a rectangular connector is a device that delivers power and/or signals between printed circuit boards (PCBs), or from a cable to its mating connector. As a memzžnine-style array connector, the FX4B3-68P-1.27SV is the perfect solution to connect two separate PCBs. More specifically, the FX4B3-68P-1.27SV features a total of 68 contacts arranged in an array orientation. This connector is great for connecting two boards that are next to each other, as there is no additional in-between system needed to transmit power or signals. Each contact is mate and retentive using C-clips, which hold the corresponding contact in place. In addition, the contact provides reliable tactile feedback when mated.

Application Fields and Working Principle

The edge-type array connector, such as the FX4B3-68P-1.27SV (71), is often used in restricted, expensive, or small areas, such as those in laptops or handheld devices. With this type of connector, the contacts are side-by-side on a narrow board, allowing for easier integration without additional wiring. This type of technology also allows a high-density population of components, or a multiple breakout style of board, resulting in a smaller size and lower costs. The edge-type array connector, such as the FX4B3-68P-1.27SV (71), works by utilizing the contact system and mate retention features to create a secure connection. Each contact consists of a male and female component, with the female contact usually having the female C-clip that allows it to mate securely with its corresponding male contact. The C-clip also serves to keep the male contact in place when the connection is made. The C-clips provide a secure fit, and the connection is usually rated up to 20 Gbps. The male contact also features an additional retention feature, which helps to keep the contacts in their desired position when mated.

Conclusion

In conclusion, the FX4B3-68P-1.27SV (71) is an edge-type array connector designed for connecting two PCBs in a high-density, space-restricted environment. This type of connector works by utilizing the contact system and mate retention features to create a secure connection. Additionally, the contacts feature an additional retention feature to maintain the positioning of the contacts when mated. In short, the FX4B3-68P-1.27SV offers an efficient and reliable solution for connecting two PCBs.
