Product Overview
The J63A Series Nano D Connectors are miniature, high-density rectangular connectors designed for aerospace, military, avionics, satellite, and other mission-critical electronic systems requiring exceptional reliability, compact size, and lightweight construction.
The J63A and J70A series share the same electrical and mechanical characteristics, differing only slightly in their external dimensions.
These connectors feature 0.635 mm contact spacing and utilize flexible twisted-wire nano contacts (Twist Pin Technology) to provide excellent electrical performance, long service life, and reliable operation under severe environmental conditions.
The plug and receptacle are secured using a screw-lock coupling system, ensuring smooth mating, secure locking, and excellent vibration resistance.
