Backplane connectors are components that can connect two or more circuit boards together electrically and physically. 50295-5140E is a specialized backplane connector designed for small form-factor applications. This article explains the application field and working principle of the 50295-5140E.

Application Field

The 50295-5140E backplane connector is typically used in small form-factor applications, such as mobile computers, tablet PCs, and mobile devices. It has a compact and lightweight design that allows for easy and efficient installation even in tight spaces. The connector has a maximum row pitch of 1 mm, which makes it well suited for use in high density PCB designs. In addition, the connector’s small size is beneficial for electronics that require a small footprint.

Working Principle

The 50295-5140E backplane connector has two parts. The first part is the "launcher," which is a rectangular board with two rows of pins arranged in a pattern. The pins are made of a plated copper alloy, which helps to reduce contact arcing and ensures good electrical connection. The second part is the "receiver," which is a rectangular board with two rows of slots in a similar pattern as the pins. The slots and pins are designed to fit together in such a way that they make contact and form an electrical connection.

The 50295-5140E connector has two lances on either side of the connector that can be inserted into holes in the PCB. When the lances are inserted, they act as retention clamps, ensuring that the connector remains securely in place. For extra functionality, the connector can also be configured with a locking mechanism that prevents accidental disconnection of the two boards.

The 50295-5140E backplane connector is rated for a maximum current carrying capability of 1A per pin and a voltage handling capability of 30V. The connector is RoHS compliant and has a maximum mating and unmating of 100 cycles. The typical contact resistance of the connector is 8 mΩ and the operating temperature range is -55°C to +85°C.

In summary, the 50295-5140E backplane connector is a specialized connector designed for small form-factor applications. This connector has a compact and lightweight design, making it ideal for high density PCB designs. The connector features a maximum current carrying capability of 1A per pin and a voltage handling capability of 30V. In addition, the connector has two lances on either side that can be inserted into PCB holes for secure retention. Lastly, the connector is RoHS compliant and has a maximum mating and unmating of 100 cycles.
