30J High Density Micro Rectangular Connector – Mini Size, Max Reliability for Precision Connection
J30J series connector is a military-grade high-density miniature rectangular electrical connector, compliant with GJB2446A standard and equivalent to MIL-DTL-83513 / MDM international specifications. Designed with ultra-fine 1.27mm pin pitch, it achieves extreme miniaturization and lightweight design, perfectly solving the connection pain points of limited internal space, dense wiring and strict weight control of high-end precision electronic equipment.Covering a full pin range from 5 pins to 144 pins, this connector supports diverse connection modes including cable-to-cable, cable-to-PCB, and PCB-to-PCB. The unique twisted pin contact structure provides excellent mechanical shock resistance and electrical stability. With professional electromagnetic shielding design and extreme environmental adaptability, it can maintain stable signal and power transmission in long-term vibration, high and low temperature, and high-humidity harsh working environments, which is far more reliable than ordinary civilian connectors.Core Advantages
Ultra-High Density & Miniaturization Design Adopts industry-standard 1.27mm ultra-fine pitch, the volume is nearly 50% smaller than traditional rectangular connectors with the same pin count. It supports 5–144 pin full-range dense wiring, effectively saving equipment internal space, reducing panel opening size, and optimizing overall equipment layout, perfectly matching lightweight and miniaturized equipment design requirements.Military-Grade Twisted Pin Reliable Connection Precision twisted pin contact structure features strong shock resistance and anti-loosening performance. It effectively avoids poor contact and signal interruption caused by equipment vibration and impact. The gold-plated contact ensures ultra-low contact resistance, anti-oxidation and stable long-distance transmission without signal attenuation or distortion.Excellent EMI Shielding & Anti-Interference Equipped with high-strength metal shielding shell, it provides excellent electromagnetic shielding effect, effectively isolating external electromagnetic signal interference. It guarantees high-precision signal transmission integrity, especially suitable for sophisticated electronic systems that are sensitive to electromagnetic interference.Extreme Environmental Adaptability Professional industrial and military-grade material formula, working temperature ranges from -55°C to +125°C. It withstands 10Hz–2000Hz high-frequency vibration and strong impact, and works stably in 98% high humidity environment, adapting to various extreme working conditions of aerospace, field and industrial equipment.Diverse Installation & Wide Compatibility Supports multiple installation methods: board mounting, wire soldering, crimping connection. Fully compatible with mainstream MDM series connectors, easy for replacement and secondary development. Flexible pin count and structural options meet the personalized matching needs of different precision equipment.Strict Military Standard Certification Manufactured in accordance with GJB2446A military standard, with stable electrical performance, high insulation resistance and strong pressure resistance. Durable plugging and unplugging cycle, low failure rate, greatly reducing equipment maintenance and replacement costs.Application Scenarios
