PC4 connectors are a type of mezzanine rectangular connectors of the edge type. Mezzanine connectors are distinguished from traditional rectangular connectors by their ability to connect two printed circuit boards at a right angle. This capability makes them ideal for applications that require stacking of boards in a tightly confined space. In this configuration, PC4 connectors offer a reliable connection, while allowing for easy removal and reconfiguration for adjustments or repairs.

The PC4 connectors are named for their ability to handle up to four pairs of high-speed differential signal pairs as well as four coaxial signals. They also possess the ability to transmit power and ground connections in both directions. This makes the PC4 connectors especially useful in applications that require the transmission of high speed digital signals or controlled impedance levels.

The PC4 connectors are designed to mount directly to the edge of the printed circuit boards. This allows them to be conveniently placed near the edge of the PCB, rather than in the middle of the board area. The connector is designed to provide a secure, reliable connection for communication between two adjacent PCBs. The interconnects can be made more reliable and robust by introducing internal double-sided contacts that are gapped across potential signal path discontinuities.

The PC4 connectors employ a stackable contact system, in which the contact arms of one connector are targeted to the pins of the other connector in alternating male and female orientations. This allows the same contact to plug into two different positions, providing a means of achieving maximum density. The wiring harness of the PC4 connector is designed for signal pairs to be routed between two or more circuit boards, thus allowing for easy passage of the signals with minimal crosstalk.

In terms of mechanical design, the PC4 connectors are constructed of high-strength aluminum, glass-filled plastic, stainless steel, and self-adhesive materials. This allows for improved durability, temperature resistance, and superior size and weight performance. The connectors are available in various sizes, ranging from 8 to 40 pins per row, and are capable of accepting a wide range of signal resolutions. The PC4 connector\'s robust design allows for its use in a wide range of applications, from industrial environments to consumer electronics.

The PC4 connectors are a cost-effective solution for many applications that require a dependable connection between two or more boards. Their performance is further improved by their ability to be quickly and easily replaced for better compatibility and greater reliability. When compared to traditional wire-to-board interconnects, the PC4 connectors offer better signal integrity and improved electrical isolation. This makes them well-suited for industrial and military applications where reliable data transmission is critical.

The PC4 connectors are an excellent choice for applications that require a robust connection for high-speed digital signals or controlled impedance levels. With their wide range of configurations, they can be used in a variety of applications including aerospace, automotive, medical, and consumer electronic products. The robust design and versatility of the PC4 connectors make them one of the most versatile and reliable mezzanine connector solutions available.
