Introduction to Rectangular Connectors - Headers, Male Pins

Rectangular Connectors - Headers, Male Pins, are electrical connectors used for a variety of purposes. Depending on the application, these low-cost, reliable connectors may have different specifications and features. Among these, 4-103330-0-37 is one of the most commonly used products.

4-103330-0-37 Application Fields and Working Principle

The 4-103330-0-37 is a one-row male pin header. It is composed of 30 pins, and its package size is 34.4mm with a height of 6.5mm. It is usually used to connect circuit boards and wires, mainly for signal transmission and current conversion. 4-103330-0-37 can be a great choice for various applications including data communication, automotive industry, medical instruments, consumer electronics, and more.

The four-digit part number for the 4-103330-0-37 mainly stands for its pitch, number of rows, number of pins, and piece count. The “0-37” at the end means the part number for its material. In this case, it’s 0 for phosphor bronze alloy and 37 for 0.45±0.03mm pin width.

The 4-103330-0-37 offers a wide range of features, such as dust resistance, high-temperature endurance, wear resistance, and high mechanical strength. It also provides excellent electrical performances with low transmission loss and a lifetime of more than 20,000 mating cycles. What’s more, the product is RoHS and REACH compliant, and is manufactured according to ISO 9001 standards.

At the same time, the pins on the 4-103330-0-37 feature a gold-plated surface, which has good corrosion resistance and insulation property. In addition, the product has a compact size, light weight, high reliability, and good stability.

As for the working principle, when a force is applied to the 4-103330-0-37, the male pin will enter into the female socket. The two elastic contacts of the pin get into the slot of the female socket and stretch up into a U-shape. This stretches the elastic mating surface of the socket, thus enabling the pin and socket to interlock.

In this kind of interlock connection, the two pin contacts allow direct current or low voltage signals. The 4-103330-0-37 also allows multiple connections of wires and circuit boards. By interconnecting the male pins and female sockets, the pin’s voltage and current limit can be adjusted accordingly.

Conclusion

In conclusion, 4-103330-0-37 is one of the most commonly used rectangular connectors - headers, male pins. It has a variety of features, such as dust resistance, high-temperature endurance, wear resistance, and high mechanical strength. It is also easy to use with a simple working principle. Its versatility makes it suitable for various applications including data communication, automotive industry, medical instruments, consumer electronics, and more.
