Product details

Locking, keying, and mounting — vibration-resistant mate

The header uses latch lock/eject hooks, long version, which provide a positive locking mechanism that prevents accidental unmating under vibration. The keying slot and mounting flange ensure correct orientation and secure board attachment.

No official second-source or cross-reference is listed by the manufacturer, but the AMP-Latch series is widely used and the 0.100" pitch footprint is a standard that crosses to other manufacturers' headers with matching receptacle housings.
