Product Overview
The J63A Series Nano D Connectors are high-density miniature rectangular connectors designed for aerospace, military, avionics, communication, and other mission-critical electronic systems. They offer outstanding reliability, compact dimensions, and lightweight construction for applications where space and performance are equally important.
The J63A and J70A series share identical electrical and mechanical characteristics, with only minor differences in their external dimensions.
Featuring 0.635 mm contact spacing and advanced Twist Pin contact technology, these connectors ensure excellent electrical performance, stable contact resistance, and long service life.
A precision screw-lock coupling mechanism provides secure mating, smooth engagement and disengagement, and exceptional resistance to vibration and shock.
