J70 / J70A

What it is

J70 and J70A — ultra-miniature rectangular connectors of the Nano-D format with a 0.635 mm contact pitch in a metal housing. According to the manufacturer, they conform to MIL-DTL-32139. The series differ in hardware thread: J70A — metric (M1.6, M2 for the 85-contact versions), J70 — inch (0-80-UNF and 2-56-UNC), so J70 mates with foreign-made Nano-D connectors.

Versions

• Cable plugs and receptacles with crimp contacts (wires are brought out in 300 mm lengths; length and color can be ordered).
• For mounting on flexible circuit boards.
• PCB versions: vertical and horizontal surface mount, right-angle and straight terminals, vertical with mounting ears.
• Hardware: jackscrew (JC), threaded insert (TH) or no hardware.
