951272-2520-AR-PR Application Field and Working Principle

Introduction

Rectangular Connectors - Headers, Male Pins, commonly referred to as AR-PR connectors are a type of electrical device primarily used in applications that require the transmission of power such as those found in automotive, telecommunications and medical equipment. The design of the connector applications range from push-in low voltage connections to high-speed data and signal applications. AR-PR connectors are available in a variety of sizes, pin configurations and materials - all of which offers the engineer a unique combination of strength, reliability and flexibility when creating their designs.In this article, the application field and working principle of the 951272-2520-AR-PR connector shall be explored.

Application Field

The 951272-2520-AR-PR connector is designed mainly for use in high-speed applications such as video, telecom, Data, Ethernet and Control systems and can also be used in automotive wiring applications. Typically, the 951272-2520-AR-PR connector has 48 or 160 signal pins and a total of 2 rows. The features and advantages of this connector make it a popular choice for high-speed and high-power applications.For high-speed data transmission, the 951272-2520-AR-PR connectors use gold plated contacts that provide higher performance than silver or copper contacts. This ensures the stability of signals and enables the data transmission rate to reach over 6 Gpbs.Moreover, the 951272-2520-AR-PR connector is suitable for transmitting high-current with its high vibration and shock resistance. The connector offers up to 10A per pin and up to 40A per line from the same line. Also, the 951272-2520-AR-PR ensures the protection of the device even in extreme environmental conditions, due to its wide operating temperature range from -55°C to 125°C.

Working Principle

The working principle of the 951272-2520-AR-PR connector, is based on a unique design that combines low contact resistance with industrial-standard miniature sized contacts and shell.The 951272-2520-AR-PR offers a durable solution to any application. The contact resistance is minimized due to the use of gold plated contacts and a durable rail spring contact system. Additionally, the connector provides high production efficiency from the automatic assembly machine and high vibration capability, due to its robust design.The shell of the 951272-2520-AR-PR connector provides reliable environmental protection and meets the requirements of most industries. The shell is composed of QMA (Quick Mount Adapter), ICE (Insulation Contact Element) and CLE (Crimp Location Element). The QMA offers quick mounting which saves time in the assembly process while the ICE is a glass filled filler material which provides the high vibration capabilities of the connector. The CLE provides the required contact force and prevents stress on the ground solder joints of the connector.To ensure the highest quality and performance, the 951272-2520-AR-PR connector also undergoes rigorous testing. The testing includes; High-frequency tests, EMI environmental tests and contact resistance tests. All tests are performed according to the requirements and standards set out by the customer.

Conclusion

The 951272-2520-AR-PR connector is a reliable, reliable and durable connector and is ideal for high-speed and high-power applications. It is designed to meet the needs of a wide range of applications, including industrial, automotive and telecom. The connector also ensures the protection of the device even in extreme environmental conditions, due to its wide operating temperature range. The connector also offers rigorous testing to ensure the highest quality and performance.
