3.96 mm pitch, 7.5 A — the Economy Power wire-to-board header
The housing is shrouded on one wall only, which guides the mating connector during insertion but leaves the top and sides exposed — a cost-reduced approach for applications where full enclosure isn't needed. A friction lock on the header provides retention against moderate vibration, common in control cabinets and lighting fixtures.
7 positions, 4 loaded — selective pin population
Only 4 of the 7 positions are loaded with tin-plated brass pins. This selective loading reduces component cost while maintaining the same housing size for polarization and keying with the mating connector. The unloaded positions remain as empty cavities — the mating housing must have corresponding blanked or missing terminals to avoid interference.
