The J30J micro rectangular connector series provides a miniature, lightweight, and high-density interconnection solution for electronic equipment requiring reliable electrical connection in a compact structure. The series conforms to GJB2446A, equivalent to MIL-C-83513, and is structurally matched with the MDM series micro connector design.

Its contact system adopts elastic stranded pin technology, commonly known as twist pin contact technology. This design helps maintain stable contact pressure, reliable electrical continuity, and good mating performance under vibration, shock, and frequent plugging conditions. The connector features a dense contact arrangement with 1.27 mm transverse spacing and 1.1 mm row spacing, making it suitable for applications requiring multiple circuits in a small installation area.

The metal shielding shell provides structural protection and helps improve signal stability. Optional metal rear covers are available for cable assembly, strain relief, and additional protection. The series includes a wide range of contact counts: 9, 15, 21, 25, 31, 37, 51, 66, 74, 100, and 144 contacts, allowing users to choose the proper configuration according to circuit density and equipment layout.

J30J connectors can be applied in cable-to-cable connection, cable-to-board connection, and board-to-board connection. PCB versions can be supplied with modified tail structures to match different board hole spacing designs. Combining high contact density, compact dimensions, flexible installation, and stable environmental performance, the J30J series is a practical rectangular connector solution for compact electronic instruments, control modules, communication devices, and test equipment.
