The J30J Series Micro Rectangular Electrical Connector is a compact, lightweight, and high-density connector designed for reliable signal interconnection in space-limited electronic systems. It complies with GJB2446A, is equivalent to MIL-C-83513, and corresponds to the U.S. MDM series, making it suitable for high-reliability electrical interconnection applications.
This series adopts elastic stranded twist-pin contacts, which provide stable contact pressure, reliable electrical conductivity, and strong resistance to vibration and impact. The connector features a 1.27 mm contact pitch and 1.1 mm row spacing, enabling high-density wiring in a miniature rectangular connector structure.
The product range includes 11 standard contact arrangements: 9-pin, 15-pin, 21-pin, 25-pin, 31-pin, 37-pin, 51-pin, 66-pin, 74-pin, 100-pin, and 144-pin. It is equipped with a metal shielding shell, and an optional metal rear cover can be selected according to cable protection and shielding requirements.
For PCB mounting applications, the connector tail can be adjusted to match PCB hole spacing. A variety of accessories are available to support different installation structures and connection methods. The J30J Series supports cable-to-cable connection, cable-to-PCB connection, and PCB-to-PCB connection, making it a versatile solution for compact electronic devices, control systems, communication equipment, instrumentation, and high-density circuit modules.
With its balanced performance in electrical capability, contact density, structural adaptability, cost efficiency, and reliability, the J30J Series is a highly practical micro rectangular electrical connector for applications requiring miniaturization, lightweight design, high-density layout, and dependable interconnection performance
