Backplane Connectors - Specialized

The 6651891-1, often referred to as the DE-9, is a special type of backplane connector used for making a connection between two PCBs (Printed Circuit Boards). A backplane connector is an electrical interconnect used to connect one or more boards together within a single device. The application fields for this connector are diverse and they touch on almost every type of device that requires robust and reliable electrical connections. Typical applications include communication systems, automation and control systems, industrial and medical equipment, as well as consumer electronics.

The DE-9 is a highly specialized type of backplane connector that is very popular with OEMs (Original Equipment Manufacturers). It is a circular connector with 9 pins arranged in three rows. The size and shape of the connector make it ideal for environments where space is at a premium. The DE-9 is designed for use in harsh environments where vibration, shock, and dust can affect the performance of the connection. The robust design of the DE-9 ensures reliable performance and a long service life.

The working principle of the 6651891-1 is based on the principle of electromagnetic coupling. This is a process where energy is transferred between two coils of wire that are physically separated. In the case of the DE-9, each pin of the connector is connected to a small coil of wire. When these coils are placed within proximity of one another, the energy is transmitted from one coil to the other via a magnetic field. This produces an electrical connection between the pins without any need for physical contact.

This type of coupling provides a reliable connection in a wide range of applications. A great advantage of the DE-9 is that it is able to resist vibrations, shocks, and dust that would otherwise damage a physical connection. This makes the DE-9 ideal for applications that require a robust and reliable connection in a space-limited environment. Furthermore, the DE-9 connector is highly resistant to corrosion and moisture, which makes it suitable for use in harsh industrial and medical environments.

The 6651891-1 backplane connector is used in a wide range of applications due to its high performance and durability. Its robust design and electromagnetic coupling principle give it great advantages in terms of reliability and resistance to environmental conditions. The small size and shape of the connector make it suitable for use in environments where space is at a premium. These features make the DE-9 connector an ideal choice for OEMs when looking for a reliable and robust electrical connection.
