Locking Ramp and Right-Angle Termination
The 0039295243: This positive lock resists vibration-induced separation in industrial and telecom equipment — a common failure mode for unlatching headers on a machine floor. The 0.142" (3.60 mm) post length gives enough solder tail for a reliable through-hole joint on standard 1.6 mm boards.
Mounting Flange and UL94 V-2 Housing
The integrated mounting flange provides additional mechanical retention to the PCB — useful when the cable assembly exerts a lever arm on the header during routing.
