Box Header Keying and Orientation Guide

Box header keying helps prevent incorrect IDC cable mating. For RFQ review, confirm the notch direction, pin 1 position, shroud shape, mating IDC socket, cable exit direction and PCB mounting style before samples or batch quotation.

Orientation details to confirm

Item	What to send	Why it matters
Pin 1 mark	Drawing, PCB silkscreen or sample photo	Prevents reversed cable or wrong harness orientation
Key notch	Front-view and top-view drawing	Confirms IDC socket mating direction
Cable exit	Photo or assembly sketch	Checks enclosure clearance and service access
Mounting style	Vertical DIP, right-angle or SMT requirement	Matches PCB process and mechanical layout
Mating connector	IDC socket drawing or part reference	Confirms latch, polarization and row count compatibility

RFQ note

If an existing box header must be replaced, send clear photos from the front, top, side and bottom. Include pitch, row count, total positions, key direction, pin 1 side, terminal tail length and plating. RoHS material compliance review is available on request when export projects require it.
