4485-0-51-80-21-27-10-0 is a type of terminal primarily used for connecting devices on circuit boards. It is small enough that it is out of the way and requires minimal real-estate on its PCB, while its sturdy contact pins allow for a reliable connection every time. It is a great way to connect chips, switches, sensors, and other electrical components.

Application Field

PC pin receptacles are mainly used in automated electronics production, which involves programming, testing, and calibration. As its name suggests, this type of terminal is also regularly used in personal computers in order to connect components like hard drives, optical drives, sound cards, and graphics cards. Since these connections are frequently used for communication with peripherals, the connection must be reliable in order to transfer data without interruption. Other industrial machinery like scanning or 3D printing solutions also use pin receptacles for communication.

Working Principle

Pin receptacles are generally made up of a pair of metal contact pins that are soldered to the board and connected to the inner contacts of a plastic housing. When the two parts are connected, the spring-loaded pins on the male terminal will push against and make contact with the electrical contacts on the female terminal. This type of connection ensures that the main electrical supply is only ever on when all the parts have been correctly aligned, and the connection remains stable even if the parts are bumped or shaken. When not in use, the pins are protected from dust and moisture by the closed housing.

In order to ensure a secure connection, most pin receptacles also use a positive latching system with a matching pair of pins and sockets. This allows the user to quickly and easily connect the pin receptacle without having to worry about misalignments. Once connected, the pins will be securely held in place until the connector is unplugged, ensuring that the connection is always safe and secure.

Advantages

Since pin receptacles take up minimal space on a circuit board, they are perfect for applications where space is limited. In fact, some pin receptacles are so small that they can be integrated directly into the PCB, eliminating the need for additional components. This makes pin receptacles an ideal choice for high-density applications, where space is at a premium. Additionally, since pin receptacles are designed to be used with low-level signals, they are well-suited for applications like motor controls, where robust signals are required.

Pin receptacles are also specifically designed to provide reliable connections, making them an attractive option for applications where signal integrity is crucial. Additionally, as pin receptacles are designed to accommodate both shielded and unshielded cable assemblies, they are a perfect choice for most industrial applications.

Conclusion

In conclusion, PC pin receptacles are a popular choice in automated electronics production due to their small size, reliable connections, and robust signal clarity. They are also well-suited for high-density applications, where space is at a premium, and industrial applications, where powered solutions are required. With a positive latching system, they ensure that the connection remains stable even during heavy use, making them an ideal choice for reliable data transfer.
