Backplane Connectors - Specialized encompass a broad range of connection types and standards, all providing various applications and capabilities. A leading example of a specialized and complex backplane connection standard is the 89025-147LF. This type of connector exhibits excellent electrical and mechanical performance, is able to perform under high power and temperature, and is a popular choice for power, signal, and data applications in many industries. In this article, we will review the 89025-147LF and its relevant fields of application as well as its working principle.

A Brief Summary of the 89025-147LF

The 89025-147LF, an abbreviation for the Amphenol Fischer Standard EDX-16 Series, is an exceptionally popular and highly specialized option amongst military and industrial applications, and is utilized worldwide. The 89025-147LF is composed of a two-part connector, which are the male and female components. The male part consists of a circular base and utilizes sixteen, 25-mm pitch power contacts. The female part also consists of a circular base, with nineteen, 25-mm pitch power contacts. Overall, these backplane connectors draw in about 13.7A of power. When the two parts are joined, the connection is formed and is mutually locked by the backplane key on each part. The 89025-147LF is fit for applications that require ultra-high temperature and shock resistance as it is able to withstand temperature fluctuations up to 220°C (428°F) and vibrations up to 10G.

Application Fields of the 89025-147LF

The 89025-147LF is used throughout all industries including: Military, Marine, Aerospace, Industrial Automation, Automobile, Medical, Telecommunications, Automation, and Test & Measurement. Of all these, Military and Automation are the two most prominent. Due to its excellent resistance to shock, dust, and vibration, the 89025-147LF makes a wise choice for military applications. Similarly, it is also highly feasible for use in industrial automation, providing connections with superior transmission performance in switchgear, automation, and motors. The 89025-147LF also supports high-speed signal transmission and performs reliably under a variety of conditions such as high temperatures, shock, dust, and corrosive environments.

Working Principle of the 89025-147LF

The working principle of the 89025-147LF is based on Twin Axial Connector technology, which makes use of a unique planar shape and key for smooth insertion. The key is designed to resist any odds of false mating. Upon each mating cycle, a pair of surface-mounted electrical contacts generates electrical contact forces that ensure reliable and durable connections. During mating, the copper metal-on-metal contacts directly contact each other. This direct contact is beneficial because the metal connection creates a better flow of current, as well as greater mechanical and thermal stability. The same mechanical stability is also created by the backplane key, which ensures the 89025-147LF does not come loose.

The 89025-147LF has become increasingly reliable and popular due to its excellent electrical and mechanical performance. Being able to endure extreme temperatures as well as reliability issues, the 89025-147LF is a preferred choice among industries such as Aerospace, Medical, Automotive, Military, Industrial Automation, and more. From the introduction of Twin Axial Connector technology to its use in applications of all kinds, the 89025-147LF\'s reliable performance and special characteristics prove invaluable in the industries in which they are used.
