Rectangular Connectors achieve electrical interconnections between a variety of printed circuit board components. Headers, Male Pins, and other types of rectangular connectors are available in a variety of contact arrangements and packages to meet different electronic connection needs. 78540-202H is widely used in rectangular connectors. This article will explain the application field and working principle of 78540-202H.

78540-202H features a 2mm pitch, three row by 20 position, both a standard mating receptacle as well as a high-tail recess and two pins for a single contact. It has a polarizing slot for horizontal orientation and features an elliptical body shape contact for ease of assembly. This connector is widely used on PCBs for various signal and power connections.

78540-202H is designed to provide a secure and reliable connection for a wide range of applications. It is suitable for both commercial and industrial applications due to its impressive performance in high-reliability environments. It can also withstand high temperatures and humidity. Furthermore, it is RoHS compliant, making it ideal for a variety of machine-building industries, including robotics, medical equipment, and consumer electronics.

The 78540-202H is a crimp contact type board-connector system. To ensure the integrity of the connection, it utilizes a high-tail layout that compensates for deflection which is caused by normal rigors of handling and installation. This contact system also allows for 360° shield capture for much higher cable strain relief. The contact system is specifically designed to reduce crosstalk to ensure a clean signal transmission path.

Moreover, the polarizing slots found on the 78540-202H are specifically designed to provide a horizontal orientation to guide the contact into proper sleeve alignment. This ensures that the contact is fully inserted before the receptacle can be fully mated. Furthermore, the elliptical body shape contact is specifically designed for ease of assembly to help save time and improve efficiency during production.

The 78540-202H’s elliptical contact was specifically designed to help reduce the contact mating force resulting from the two-step crimping during assembly. This two-step process helps to improve the service life of the connectors. Moreover, the contacts offer full-shieldcapture capabilities to help reduce the wear and tear on the connector and increase the component life when used in difficult hostile environments.

In conclusion, the 78540-202H is a versatile board-connector system with a 2mm pitch three row by 20 position contact configuration. It has an impressive performance in high-reliability environments and its elliptical body shape contact with two-step crimping is specifically designed to provide secure and reliable connections. It is ideal for use in a variety of machine-building industries, and its 360° shield capture feature helps to reduce crosstalk as well as extend the product’s lifespan even in harsh environments.
