Rectangular Connectors - Headers, Male Pins, are a type of electrical component used in the PCB assembly industry. They are designed to provide a reliable connection between two devices, primarily from the PCB to the components they must power. The 87543-4 ​​is a type of Rectangular Connector - Header equipped with male pins. It is used extensively in industrial and consumer electronic products.

The 87543-4 consists of a two-piece body made of thermoplastic material known as ABS or Polycarbonate. It is RoHS (Restriction of Hazardous Substances) compliant, with male pins made of tinned phosphor bronze contacts. The 87543-4 has an operating temperature range of -40°C to 105°C and a voltage rating of 30 V. The male pins are arranged in 3x2, 3x6, 5x3, and 10x4 patterns. This mating connector is available in a range of sizes from 4.2mm to 20mm.

The 87543-4 is mainly used in a variety of digital circuits, electronic circuits, and signal/power connection applications to ensure a reliable and secure connection. It is designed for applications that require a high level of electrical performance, such as power output, power input, signal transmission, and signal filtering. For example, HDMI and USB sockets, ATA cables, and various sensors and transducers can be linked with the 87543-4.

The working principle of the 87543-4 is simple. The electrical connection is established when the two parts, the header and the pin, are pressed together and the spring-loaded metal clips of the pins bite into the friction strips on the inside of the header. This ensures a secure and reliable connection, and the contact pressure of the spring-loaded clips keeps the connection in place.

The 87543-4 offers a number of advantages over other types of electrical connectors. It is easier to install, compared to other connector types, due to its smaller size. The presence of metal clips ensures that a reliable connection is maintained even between devices with large gaps. And, since the pins are made from corrosion-resistant materials, contact degradation is unlikely.

In summary, the 87543-4 is a small and inexpensive electrical connector that can be used in a wide range of applications. It is RoHS compliant and provides reliable connections with its spring-loaded metal clips. The header and pin mating design makes it easy to install, and the corrosion-resistant materials provide a robust connection that will last for a long time.
