Backplane connectors are specialized cables that allow the electronic devices and cables to be connected. The 91570-103 backplane connector contains a specialized contact design and is used in applications that require high-density backplane connectors. This article will discuss the application field and working principle of the 91570-103 backplane connector.

Application
The 91570-103 backplane connector is a high-density backplane connector used in applications where superior contact reliability is essential. It is designed for applications such as rack-and-stack systems, industrial control, telecom, and mobile communication systems. It can also be used in intensive computing systems where high speed and reliability are essential. The connector supports up to 26 contacts and is rated for 240VAC, 600VAC, and 2000VAC.

Working Principle
The 91570-103 backplane connector utilizes a specialized contact design called a floating-lens contact. This contact design uses a spring-loaded contact lens, which is mounted in a floating frame. These contacts are held in place by two flexures that expand and contract with temperature changes. This allows the contacts to expand and contract when the temperature around the contact rises and falls, ensuring optimal contact with the mating surface. The contact area on the lens is ring-shaped, providing consistent contact with the inner and outer conductors of the cable.

The 91570-103 backplane connector is also designed with a housing that is self-extinguishing and does not support combustion. This helps keep the connector cool and prevents arcing from occurring, which could cause damage to the connector or surrounding components. The contact is also rated for temperatures of 0-105°C and a maximum of 3,000 mating cycles, ensuring reliable and dependable performance.

The 91570-103 backplane connector also uses an alternate pin layout design that helps reduce electromagnetic interference (EMI). The design actually separates the four metal shielding layers, making it easier for the EMI to dissipate. This helps reduce crosstalk and helps prevent EMI from disrupting data transfers.

Conclusion
The 91570-103 backplane connector is a high-density backplane connector designed for applications where superior contact reliability is essential. It utilizes a specialized contact design that provides consistent contact over a large temperature range and is self-extinguishing. The connector also utilizes an alternate pin layout design to help reduce EMI and helps keep data transfers reliable. All of these features make the 91570-103 backplane connector an excellent choice for the most demanding applications.
