Through-hole header with locking ramp for vibration-prone wiring
It uses a locking ramp fastening type that clicks into the matching receptacle housing, preventing accidental disconnect under vibration or cable strain. The 4.20 mm pitch and 0.165" row spacing give generous clearance for routing thicker power wires alongside signal lines.
How the 13 A rating changes your power budget
At 13 A per contact, this header can carry up to 156 A across all 12 positions (assuming balanced load and proper derating). That is roughly 44% more current than the 9 A per contact of the ATX-series peer 4-1775099-7 at the same 4.20 mm pitch, making the VAL-U-LOK HCS variant a better fit for power-distribution boards in lighting or industrial control. Compared to the 1379030-3 header at 2.54 mm pitch with a friction lock, the 1-2825260-2 offers a wider pitch (4.20 mm vs 0.100") and a positive locking ramp instead of a friction lock, which improves retention in high-vibration assemblies.
