Introduction

Rectangular connectors have become the industry standard for connecting electronic and electrical components together. This type of connector comes in a variety of sizes and configurations, the most common being the 3mm header pin (often referred to as 103311-3). 103311-3 headers are widely used in the automotive and consumer electronics industry due to their low cost and ease of use.

Application Field

The 103311-3 headers are a popular choice for applications such as automotive, LED lighting, industrial and consumer electronics, and other applications requiring a reliable, cost-effective connection.

In automotive applications, the 103311-3 headers are ideal for power distribution, communication, and controlling various electronic components. Connectors used for power distribution typically use multiple pins to ensure reliable and secure connections between components. This type of header also works well as a communication tool for ECU modules, and controlling the various components found in a modern car, such as LED headlights and other electronics.

In industrial applications, the 103311-3 header is often used to connect sensors and relays. These components are used to detect changes in the environment, such as temperature or pressure, and are also used to control motors. Because of its low cost and reliability, the 103311-3 header is also widely used in consumer electronics, such as cell phones, computers, and other electronic products.

Working Principle

A 103311-3 header is a type of connector that uses pins to create a reliable and secure connection. The pins are typically arranged in two rows facing opposite directions. Each row contains a set of three or four pins tightly fitted into the header. The pins are surrounded by a plastic housing which is used to protect the connection while ensuring proper alignment.

The pins are connected to the internal circuitry through a series of metal probes which are secured inside the housing. When the pins of the header come into contact with the metal probes, the connection is formed. This connection allows the current to flow between the connected components, allowing whatever device is connected to the header to function.

The 103311-3 header also utilizes the advantages of a secure locking mechanism which prevents accidental disconnection between the component and the header. This is done by inserting a locking spring between the metal probes and the pins to ensure that the connection remains stable. This type of locking system is very reliable and durable, making it perfect for applications that require secure connections.

Conclusion

The 103311-3 header is a popular choice for many different applications due to its low cost and ease of use. It is widely used in the automotive and consumer electronics industry due to its reliable and secure connection. The header also utilizes a locking mechanism to ensure that the connection is stable and secure. This type of header is ideal for applications that require reliable connections between components.
