Rectangular Connectors - Headers, Male Pins, commonly known as "399-40-155-10-009000", are an important type of electrical connector. They are widely used to connect two circuits and provide a link between them. This type of connector is rectangular in shape, with a pin on either side that fits into a corresponding female receptacle. The pins are usually color-coded to indicate power levels, or signal designations.

The application of rectangular connectors ranges from consumer electronics to high-performance industrial equipment. In a typical application, a header is mounted on a printed circuit board and connected to a female connector, usually via crimping or soldering. This allows for easier debug and repair of circuits, especially with digital or analog designs where troubleshooting may be needed.

The working principle of Header Male Pins is quite simple. The pins fit into the female receptacle and make contact, creating a secure and electrically sound link. It is important to ensure that the size and pitch of the pins is appropriate for your application. If the pins are too small, they may not make firm contact and will fail. Too large of pins can cause arcing, short-circuiting, and other forms of interference.

Pin contacts can be made from various materials, including brass, copper, aluminum, and stainless steel. The choice of material is determined by the application\'s environment and its requirements. For example, brass is not suitable for high-temperature or high-vibration applications. In most cases, brass pins are preferred for lightweight consumer applications due to their low cost and good electrical conductivity.

The conductivity of the pins is also important. Pins that are too conductive can cause circuits to experience significant current leakage, which can reduce performance and potentially create safety hazards. Low-conductivity pins, on the other hand, can result in incorrect signals or even cause the circuit to fail.

Finally, the header pins are protected against wear and tear with two types of insulation: plastic and metal. The plastic insulation prevents short-circuiting and improves resistance to vibration, shock, and temperature extremes. The metal insulation provides extra strength and rigidity, providing additional protection against wear and tear.

In conclusion, Rectangular Connectors - Headers, Male Pins are an essential component in many electrical systems. They are easy to install and require minimal maintenance. When choosing the correct type for an application, it is important to consider the size, pitch, material, and insulation of the pins as well as the environmental conditions.
