516-090-521-402, commonly known as the Type 4 connector, is distinguishable by its signal-driven pin connection and press-fitted interface. It belongs to a class of backplane connectors known as specialized connectors, which consist of the backplane components used primarily for switch and bus bar systems. These specialized connectors were developed during the 1980s as part of the effort to reduce the overall size and weight of electronic components, resulting in a greater efficiency in the backplane assembly.

A Type 4 connector features a connector body that is die-cast from zinc alloy, and a series of five pins on one side. The pins can be either 2.5mm or 3mm in diameter and can be inserted or removed with a simple press-in/press-out motion. The other side of the connector body is equipped with an injection-molded contact, designed to provide a secure and reliable connection that will not be disturbed by frequent vibration or extreme temperatures.

The primary application of a Type 4 connector is in the form of a bus bar or switch connection. This type of connection is used in many industrial applications, such as automotive and aerospace applications, where signals need to be exchanged in a stable, reliable, and secure manner. A typical example of a Type 4 bus bar connection would involve a controller, connected to a number of sensors and controllers, which is enabled by the connection of the pins in the Type 4 connector.

The working principle of a Type 4 connector mainly relies on the two parts: the connector body and the injection-molded contact. The connector body allows the pins to be inserted and removed with a simple press-in/press-out motion. The injection-molded contact then provides a secure and reliable connection that will not be disturbed by frequent vibration or extreme temperatures. It is this combination that ensures a highly durable and reliable connection designed to last.

In summary, the Type 4 connector is a specialized backplane connector that is used mainly as a bus bar or switch connection. It consists of a die-cast zinc alloy connector body and injection-molded contact that provides a secure and reliable connection that is not disturbed by vibrations or extreme temperatures. This makes it suitable for many industrial applications where signals must be exchanged in a stable, reliable and secure manner.
