Rectangular Connectors - Headers, Male Pins

Rectangular connectors, also known as headers, male pins, and surface-mounted connectors, are versatile and robust connectors that are used in a variety of applications. This article will discuss the application field and working principle of the 4-103327-0-25 rectangular connector.

Application Field

Rectangular connectors, such as the 4-103327-0-25, are used in a wide array of applications, such as circuit board assembly, power and signal connections, and printed circuit board (PCB) interconnections. They can also be used in more demanding industrial applications, such as electrical and electronic equipment, high power motors, and in automotive applications. The 4-103327-0-25 is particularly suited for high speed data communications applications.

Working Principle

The 4-103327-0-25 rectangular connector is a two-piece connector meant for connecting electronic components with boards. It consists of two components: the male pins, which are inserted into the board, and the female headers, which are attached to the board. The male pins are generally made of brass or copper, and are pre-installed onto a solderable PC board. The female headers are mounted over the pins and the pins are then soldered into place.

Once the pins have been soldered into place, the connection between the headers and the pins is made. A positive contact is made between the pins and the headers through the use of compression, which is done through the use of springs or snaps. This creates a tight connection that is resistant to vibration and shock. The connection is then sealed by a flexible polyester or silicone insulator, which helps protect against dust, moisture, dirt, and other contaminants.

The 4-103327-0-25 rectangular connector has a current rating of 16A, a voltage rating of 600VAC/200VDC, and an operating temperature range of -25°C to 85°C. It is UL rated and meets RoHS and REACH standards. It is RoHS and REACH Compliant, meaning that it is non-toxic and is free of hazardous chemicals. It is also IP67 rated, meaning it is dust-tight and resistant to water and oil.

Conclusion

The 4-103327-0-25 rectangular connector is a versatile and robust connector that is suitable for a variety of applications. Its two-piece construction ensures a secure connection between the male pins and the female headers. It is UL rated and meets RoHS and REACH standards, and is rated for both dust-tightness and protection against water and oil. The 4-103327-0-25 is particularly suited for high speed data communication applications.
