Backplane connectors are a type of electrical connector designed to connect a printed circuit board (PCB) to other electronic components. They are commonly used for data and power communication between multiple PCBs, and serve as a physical interface for electrical signals. The PCN21B-125SB-2PF-G is one such backplane connector which belongs to the Hard Metric Standard category.

The Hard Metric Standard backplane connectors are a series of standardized, high-performance, multi-contact connectors designed to meet the demanding requirements of modern electronic systems. They are available in several different sizes to fit a range of board-to-board and board-to-flex cable applications. The PCN21B-125SB-2PF-G is a medium-size Hard Metric Standard connector with 12 rows, 125 contacts per row, and 2 position flange for mounting.

The PCN21B-125SB-2PF-G can be used in printed circuit boards, such as in communications, enterprise and military applications. It is designed for increased speed and signal integrity, making it well-suited for high-speed data transfer applications. It has a 550A-rated contact retention force, a current rating of 3A, and a maximum operating voltage of 250VAC.

The PCN21B-125SB-2PF-G has a simple but effective and reliable mechanism for connecting its two metallic portions, comprising of one non-moving “male” with pins and the other “female” with grooves to accommodate the pins. Its two halves come in two pieces, each held together by hard retainers. When the halves are placed together, the pins and grooves come in contact with the hard surfaces of the retainers, providing a secure connection that won’t loosen over time.

In addition, the PCN21B-125SB-2PF-G has been designed to be both RoHS-compliant and UL-approved, making it an ideal choice for use in printed circuit boards. It also meets MIL-STD-2041, MIL-STD-2111, and MIL-STD-2100/A standards. This ensures that it is reliable and safe for use.

The PCN21B-125SB-2PF-G is a high-performance, reliable, and cost-effective backplane connector, suitable for applications requiring high speeds and signal integrity. Its contact design provides superior electrical performance, resulting in fewer signal reflections and less noise. Furthermore, its robust design and UL-approved construction makes it an ideal choice for applications where reliability is paramount.
