Introduction

The 20021321-00074T4LF is a rectangular connector header from Glenair, an established manufacturer of high-precision, tight tolerance rectangular connector systems. It is part of a large family of other Glenair products, such as heads, receptacles, female sockets, and more. This particular product is typically used for applications that require highly reliable electrical connections of low-level signals in demanding environments.

Application Areas

This particular header is best suited for applications that require low-level, reliable, and low-impedance signal connections in demanding environments. These may include board-to-board interconnects, tight tolerance electronics applications, high bandwidth requirements, and in automated systems.The 20021321-00074T4LF is an ideal product for highly reliable and consistent performance in both low-level and high-level applications. It is able to deliver high-speed performance even in challenging, hostile environments.

Construction and Features

This connector header is made from a rugged die-cast aluminum housing and contact areas that are plated with RoHS compliant gold plating. The product is also rated up to 500 mA for dc current in an ambient temperature range of -40°C to +105°C. The connector features a snap-on "teeth" latch that ensures a secure and reliable mating interface.The connector also features a low-intrusion spring pressure contact system. This ensures a low contact force between the contact pins and board connections. This allows for extremely reliable signal integrity performance in high speed applications. The contacts are also rated for up to 500 mating cycles, which makes it ideal for long-term use.

Working Principle

The 20021321-00074T4LF connector header utilizes a simple and straightforward worked principle. First, the "teeth" latch on the side of the connector are snapped into place in order to secure it in place. The pressure contact system then works to ensure a low contact force between the contact pins and board connections. This ensures the reliable and consistent performance of the connector in both low- and high-speed applications.The contacts on the connector header are designed to have a low contact resistance, which is very important for reliable signal integrity. The contacts are also rated for up to 500 mating cycles, which ensures the connector can last for a long time.

Conclusion

The Glenair 20021321-00074T4LF is a highly reliable and versatile rectangular connector header. It is ideal for applications that require low-level, reliable and low-impedance signal connections in demanding environments. The connector is built using an aluminum housing and RoHS compliant gold plating on the contact areas. It is also rated to handle up to 500 mA of dc current and up to 500 mating cycles. The contacts are designed to have a low contact resistance, which ensures reliable signal integrity. It is an ideal product for a variety of applications.
