PCN21B-125SB-2PF backplane connectors are widely used in the field of high-speed computer processing and signal transmission. These backplane connectors are designed to provide high rate data transmission between multiple printed circuit boards (PCBs) and other electrical devices. This article will give an overview of the working principle and application field of PCN21B-125SB-2PF backplane connectors.

PCN21B-125SB-2PF backplane connectors belong to the Hard Metric, Standard type. The main components of the connector are pins, sockets, screws and a dielectric layer. The pins and sockets have a diameter of 21mm. The dielectric layer is made of FR-4 glass-reinforced epoxy whereas the screws are made of zinc-plated steel. The voltage rating of the connector is 125VAC and the current is 2A. This backplane connector is rated for operation up to 200 MHz. It supports up to 96 differential pairs and has a clear signal integrity at up to 100 Gbps.

The working principle of the PCN21B-125SB-2PF backplane connector is based on the connection between the pins and sockets through the screws. The tight contact between the pins and sockets creates the electrical connection. Once the pin and socket are engaged, the screws are tightened. This locks the connectors in place. The dielectric layer prevents any interference from surrounding circuits, further ensuring a robust connection. The screws provide additional reinforcement to guarantee the reliability of the connection.

These backplane connectors are widely used in various industries. They have been used in a variety of areas including communication networks, data storage systems, industrial automation, military and aerospace, and medical and laboratory equipment. PCN21B-125SB-2PF connectors are especially suitable for high-speed interconnect systems, where high speed and low crosstalk are most important. These connectors are also used for high-dynamic systems such as x-ray machines, where the frequency and voltage range are very important.

In conclusion, PCN21B-125SB-2PF connectors are a reliable and efficient way to connect multiple Printed Circuit Boards and electrical devices. Their high voltage rating, superior signal integrity and excellent durability make them ideal for a variety of applications. They are commonly used in communication networks, data storage systems, industrial automation, military and aerospace, and medical and laboratory equipment.
