| High Light | 51 Contact Rectangular Connector ，Micro Rectangular Connector ，High Density connector rectangular | ||
The J30J series high-density micro rectangular electrical connector provides a reliable connection solution for electronic systems requiring miniaturized structure, lightweight design, and stable multi-contact performance. The product is manufactured according to GJB2446A, equivalent to MIL-C-83513, and is structurally aligned with the MDM series micro rectangular connector family.
The connector uses elastic stranded contacts, often referred to as twist pins, to achieve reliable mating and stable electrical contact. This contact structure is suitable for applications where vibration, shock, repeated insertion, and limited installation space must be considered. With a 1.27 mm horizontal pitch and 1.1 mm row spacing, the J30J series provides high contact density while maintaining a compact rectangular outline.
The metal shielding shell improves protection for the contact system and helps support stable signal transmission. A metal rear cover is available for applications requiring additional cable protection or assembly support. The series is available in multiple contact counts, including 9, 15, 21, 25, 31, 37, 51, 66, 74, 100, and 144 pins, covering different low-density and high-density circuit layouts.
This connector series supports cable-to-cable, cable-to-PCB, and PCB-to-PCB connection forms. Board-mount products can be supplied with tail modifications for different PCB hole spacing. With balanced performance in electrical reliability, contact density, mechanical adaptability, and cost efficiency, the J30J series is well suited for compact equipment that requires durable rectangular connector interconnection.
