J30JM1 Series Product Introduction
The J30JM1 Series is a high-reliability hermetic glass-to-metal sealed connector designed for aerospace, military, avionics, and other mission-critical electronic applications. The receptacle features a glass dielectric insulator, 1.27 mm contact spacing, and fully gold-plated socket contacts, ensuring excellent electrical conductivity, corrosion resistance, and long-term performance.
The mating plug incorporates twisted flexible (braided) contacts, providing smooth insertion and extraction with low mating force. Available in 5, 9, 11, 13, 15, 21, 25, 31, and 37-contact configurations, the J30JM1 Series is suitable for compact, high-density interconnection systems.
Manufactured in accordance with GJB2446A, these connectors offer outstanding hermetic sealing, excellent resistance to vibration and shock, and reliable operation in harsh environmental conditions.
