The square pin contact (phosphor bronze) provides a reliable solder joint and consistent insertion force into the receptacle. The keying slot in the shroud ensures the header can only mate with a receptacle that has the matching key, preventing reverse or offset insertion on the production line or in field service.
The keying slot is a physical notch in the 4-wall shroud that aligns with a matching key in the AMP-Latch receptacle. It prevents the header from mating with an unkeyed or wrong-keyed receptacle, reducing assembly errors.
