Board-to-Wire Power Header for Enclosed Equipment
The 2029056-3: It carries a 9A per-contact rating at 600VAC, with tin-plated male pins on a 4.20mm pitch. The shrouded 4-wall housing and locking ramp provide positive retention and pin protection in moderate-vibration environments typical of general-purpose industrial and lighting equipment.
Mating Half and Assembly BOM
This header mates with a VAL-U-LOK receptacle housing (e.g., 1-480700-0 series) using the corresponding crimp terminals. The build-to-print BOM should include the header, the receptacle housing, and the crimp contacts — all sold separately.
Comparison with Peer 4-1775099-7
The closest functional peer is TE's 4-1775099-7, a 20-position dual-row header in the ATX series with the same 4.20mm pitch and 9A rating. The 2029056-3 is a single-row, 3-position variant — the dual-row peer carries thicker post plating (120µin vs 80µin) and a higher position count, but shares the same locking ramp and shrouding.
