Rectangular Connectors are very popular due to their simple construction, reliable performance and economic cost. The 68710-422A is one example of a rectangular connector and it is specifically designed for high-density signal applications. This article will provide an overview of the 68710-422A application field and working principle.

The 68710-422A is a two-row, high-density board-to-board connector. It features a 4 mm square pitch with a 0.8 mm contact pitch, four stacks (rows) with 24 positions per stack and contains a total of 96 contacts. Its solder tails are designed with a lead-free solder-retention feature, which ensures that the connectors remain securely in place through continual operations.

The 68710-422A is an ideal solution for various applications, such as local area networks, panel-mount devices, telecommunications devices, medical devices, high-density wiring harnessing, servers, and LCD displays. The board-to-board connector is able to transmit high-density signals and power with a maximum current rating of 3.0A per position. It is available in two types of mating system – 2.0 mm A Type (Top Contact) and 2.2 mm B Type (Bottom Contact). The latter is designed for thinner boards.

The 68710-422A is equipped with a positive lock system that includes earth retention and keying fingers for unique-key mating. This feature allows users to create unique mating keys in order to prevent any cross mating or pin contact misalignment. In addition, the connectors also provide dust and water proofing via a special dust cap and an O-ring that forms a closed and sealed box.

When it comes to work principle, the 68710-422A utilizes a crimp terminal connecting method. The signal contacts feature 0.5 mm-thickness metal shells with a crimp termination. The terminals will then be automatically soldered onto the printed circuit boards. This process significantly reduces soldering time and provides long-lasting durability.

Overall, the 68710-422A provides reliable performance with its positive lock system and crimp terminal connections. It is often used in various high-density applications such as LANs, medical equipment, panel-mounted devices, etc. It also proves its reliability with a maximum current rating of 3.0A per position and withstands extreme temperatures with an operating range from -20°C to +105°C.
