Backplane connectors are key components in data and communication systems as they provide the primary connection between PCB boards or even systems. They are usually used in critical applications where high-speed signal transmission and multiple termination points are needed.PCN21B-SA-G is one of the most commonly used backplane connectors.This article is to discuss its application field and working principle.

Application Field of PCN21B-SA-G Backplane Connectors

PCN21B-SA-G backplane connectors are often found in communication and data system applications in order to create the necessary connections between systems, boards and devices.This connector is designed for use in high-demand applications with high-speed signaling and multimode operation.It is easy to install and replace, and offers a shallow profile, making it suitable for use in most spaces.The durability of the product can also be guaranteed due to its ability to withstand temperature, shock, vibration, and humidity.

The PCN21B-SA-G backplane connector is often available in a variety of configurations for data centers, telecom base stations, and large-scale networking applications such as routers, switches, and hubs.

Working Principle of PCN21B-SA-G Backplane Connectors

PCN21B-SA-G backplane connectors use a paralleled contact design in which both sides of the board are mated together.This contact design allows for shorter signal paths, and therefore higher data rates.The pins of the backplane connector are held in contact with the through-holes via the use of pressure fingers.The pressure fingers push the pins into the through-holes, and hold the connection in place.The contact is then isolated from the outside environment by an insulating material, preventing any corrosion or oxidation on the pins and ensuring a reliable connection.

When the power is applied to the backplane, it causes a high-frequency current to flow through the pins and contact the pressure fingers.This current creates a lower resistance path so that signals can be transferred from one circuit to another.The PCN21B-SA-G backplane connector also offers an additional secure locking system to ensure that the connection is stable and robust.The connector also has a built-in strain relief feature to protect the pins from any mechanical damage.

Conclusion

PCN21B-SA-G backplane connectors are a reliable and durable way of connecting boards, devices, and systems.They are often used in communication and data systems for high-speed signal transmission, offering a shallow profile, and a secure locking mechanism.The connector is also able to withstand temperature, shock, vibration, and humidity with ease.Their parallel contact design allows for shorter signal paths and greater data rates, making them suitable for use in data centers, telecom base stations, and large-scale networking applications.Overall, the PCN21B-SA-G backplane connector is an excellent choice for reliable and efficient connection.
