87527-4

Rectangular Connectors, commonly referred to as Headers and Male Pins, are generally used to connect two different pieces of electrical equipment in an orderly manner, transferring signals from one piece of equipment to the other. This type of connector has many advantages over its counterparts, but it is essential to understand the application and working principle of the specific connector in order to choose the correct type for the desired application. 87527-4 is a header-style connector, used for both signal and power transmission. This article will discuss the application field and working principle of 87527-4.

Application Field

The 87527-4 is a 4mm pitch, polarizing R/A header. Its size and configuration make it suitable for a number of applications, ranging from printed circuit boards (PCBs) to specialized, high-density equipment. These connectors, also called terminal blocks, are commonly used for mounting onto the board or relocating connections when introducing new components. 87527-4 is especially suitable for creating compactly laid-out circuits, either side of the board. This connector can be used to join several different types of equipment such as LED drivers, temperature sensors, switches, and other components.

Working Principle

The 87527-4 is a 4mm-pitch, iron shell, polarizing connector with 4-poles configuration. Its operating temperature range is between −20°C to +105°C, which makes it suitable for a wide variety of applications. It has an internal wire to board connection, and the polarizing feature helps prevent misconnections. The contact between the board and connector is made through normal insertion and removal forces, which are regulated by a robust contact spring. This ensures secure and reliable contact in a variety of different conditions. The connector has a current rating of 1.5A and a voltage rating of 250V AC.

In addition, the 87527-4 connector has a polarized keyed housing, as well as two positions to mate the male and female counterparts. This means that the connections are held securely in place, and the cables are prevented from making contact with each other; thus, preventing any short circuiting or wrong connections between them. Furthermore, the connector ensures maximum EMI (electromagnetic interference) performance due to its low-profile design and plastic material.

Conclusion

The 87527-4 is a 4mm pitch, polarizing connector that is suitable for a variety of applications, ranging from printed circuit boards to specialized, high-density equipment. The connector offers a secure and reliable contact between the board and connector, and its low-profile design ensures maximum EMI performance. Moreover, the 87527-4 has two positions to mate the male and female counterparts, preventing any short circuiting or wrong connections between them. It is an excellent choice for creating compactly laid out circuits, either side of the board.
