Board-to-cable/wire header with locking ramp

Loaded positions and sourcing posture
What mates and what to check
This header mates with a corresponding cable/wire receptacle (not included). The 3 loaded positions mean the header is partially populated — verify the exact circuit count needed for your harness. The 0.114" (2.90mm) post length suits standard through-hole PCB thicknesses.
