XH4A-4031-2A is a kind of array edge type mezzanine (board to board) rectangular connector, which integrates multi-needle array connection technology and quick-connect screw self-locking technology. It is designed with two rows of 40 pins, 4x35mm2 pitch, single-row and two-row structure, all integrated into a single-row, double-row connector. Due to its excellent features and convenience of installation, it is especially suitable for the applications of industrial automation, machine tables, scanning systems, display systems, personal computers, communication equipment, instrumentation, and so on.

This kind of rectangular connector is equipped with mated self-locking screws, which can be quickly connected and locked, following the corresponding threaded grooves of the backplane. The locking screws are also designed with a geometry that allows the user to actuate the locking without the need for any tools. On the other hand, this connector also has many other advantages, such as low contact resistance, high compressive strength, corrosion-resistant material, low temperature rise, and so on.

In general, this connector uses two rows of 40 multi-needle array connection terminals. These terminals are arranged at an interval of 4x35mm2 pitch to ensure reliable connection between electronic components. The contact pins of the XH4A-4031-2A connector are embedded in a dielectric material, providing a reliable electrical connection and avoiding any possible electrical interference. Additionally, the plugs are designed in a single-row and two-row structure, allowing the user to choose the best one to meet their application requirements.

In terms of working principle, the XH4A-4031-2A mezzanine connector follows the same concept as other kinds of rectangular connectors. Its terminals are arranged in a dual row of 40 pins and are connected to each other through a double-row quick-connect locking screw. The contact pins are made of high-quality metal with corrosion-resistant material, providing a reliable electrical connection. Furthermore, the two different contact pins for the backplane and the device are securely mated and latched by the locking screws, providing reliable locking between the two connections that is both efficient and secure.

To sum up, the XH4A-4031-2A is an excellent example of array edge type mezzanine connector that can be used to provide excellent and safe connection between devices. Its features and advantages make it especially suitable for many applications such as industrial automation, machine tables, scanning systems, display systems, computers, communication equipment, and instrumentation. Moreover, its easy installation and quick-connect locking screw provide an efficient and reliable connection. Therefore, the XH4A-4031-2A is a very popular type of connection solution and is widely used in the market.
