J63A Series Nano D Rectangular Connectors
Product Overview
The J63A Series Nano D Connectors are ultra-miniature, high-density rectangular connectors engineered for aerospace, military, avionics, satellite, and other mission-critical electronic systems. The J63A and J70A series share identical electrical and mechanical performance, differing only in external dimensions.
Featuring advanced Twist Pin flexible Nano-contact technology with a 0.635 mm contact pitch, the J63A series provides outstanding electrical reliability, excellent vibration resistance, and a compact, lightweight design. The connectors are secured using a precision screw-lock coupling system, ensuring smooth mating and reliable locking even in harsh operating environments.
Available in 5, 9, 15, 21, 25, 31, 37, 51, 65, 69, and 85 contact configurations, the J63A series is ideal for applications requiring high-density signal transmission with minimum space and weight.
