Backplane connectors are specialized connectors that are designed to efficiently connect backplanes to device circuits. The 7021-1101LF connector is one such example. This article will discuss the application field of this connector, as well as its basic working principle.

Application Field

The 7021-1101LF backplane connector is designed to offer high-speed, high-density signal and power applications in industrial and aerospace applications. It is a compact, low-profile connector that is ideal for applications where space is limited. It also features low insertion force contacts that provide a secure and reliable connection.

The connector is a great choice for power applications, offering up to 10 A (15 A peak) of power per line. This makes it an ideal choice for high-power applications, such as LED lighting systems. It also has an operating temperature range of -55ºC to +125ºC, making it well suited for industrial environments. The connector is also RoHS-compliant, making it an environmentally friendly choice.

Working Principle

The 7021-1101LF connector works by utilizing magnetic actuation. Each contact in the connector is made up of two opposed pins, which are connected to a gold-plated beryllium copper spring in the middle. This spring acts as an actuator, and when current is applied, it creates a magnetic field that pulls the pins together, creating a connection.

The pins are also designed to be self-aligning, meaning that when they are connected, the actuator will pull them into the correct position. This ensures a secure and reliable connection and prevents accidental disconnection. The contacts also have a low insertion force, making it easy to connect and disconnect the connector.

The 7021-1101LF connector is a compact and reliable solution that is well suited for high-power and high-density applications. Its low insertion force contacts and self-aligning pins ensure a secure connection, while its wide operating temperature range makes it ideal for industrial environments. The connector is also RoHS-compliant, making it an environmentally friendly choice.
