J30JM1 Series Hermetic Glass-Sealed Connectors
Product Overview
The J30JM1 Series features high-reliability glass-to-metal hermetic connectors designed for aerospace, military, defense, avionics, communication, and industrial electronic applications. The receptacle utilizes a glass dielectric structure to provide exceptional hermetic sealing, excellent electrical insulation, and long-term reliability in harsh operating environments.
The connector incorporates gold-plated contacts with a 1.27 mm contact pitch, ensuring low contact resistance and excellent conductivity. Compatible plugs use twisted flexible (braided) pins, providing smooth mating, low insertion force, and reliable electrical performance.
Available in 5, 9, 11, 13, 15, 21, 25, 31, and 37-contact configurations, the J30JM1 Series complies with GJB2446A military standards and is ideal for applications requiring compact size, vibration resistance, and airtight sealing.
