Frequently Asked Questions
What circuit board thickness does this connector accept?
It is designed to mate with standard 1/16-inch (0.062 in or 1.57 mm) thick printed circuit boards.
What is the pin spacing and total contact count?
The connector features 44 total contacts arranged in two parallel rows of 22 contacts on 0.156-inch (3.96 mm) center-to-center spacing.
Can this connector be secured directly to a chassis panel?
Yes. The integral mounting flanges on both ends include pre-formed holes for hardware mounting directly to a card cage, chassis plate, or rack frame.
Wire-wrapping might be a lost art to some, but nothing beats the reliability of a solid point-to-point backplane when keeping classic hardware running. Slot your card, spin your posts, and make the connection count.
