20-Position VAL-U-LOK Receptacle Housing for Wire-to-Board Harnesses
The TE Connectivity VAL-U-LOK 2-1586019-0 is a 20-circuit, dual-row receptacle housing built for wire-to-board power interconnects.
Housing Specs and the Fit Decision
The 4.20mm pitch gives enough room between circuits for the current each contact carries — typically 5 A to 9 A per circuit depending on wire gauge and temperature, though the exact derating depends on the chosen terminal. The dual-row layout with 0.165" row spacing keeps the connector body compact for a 20-position power connector.
This receptacle mates with the VAL-U-LOK plug housings (male pin side, 2-1586017-x series) in the same 4.20mm pitch and row count. For a 20-circuit mated pair, the matching plug is 2-1586017-0. The female socket contacts (not included) are crimp-terminated; the recommended wire range is 18-22 AWG for standard power duty, with the specific terminal part number depending on wire size and plating (tin vs gold). Order the housing and the terminals as separate line items on the BOM.
