What This 14-Position Plug Housing Is — and the Trap to Avoid
The TE Connectivity VAL-U-LOK 1-1586861-4 is a 14-position plug housing in the 4.20mm-pitch series, designed for wire-to-wire or wire-to-panel interconnect in power and signal harnesses. The 0.165" (4.20mm) pitch gives enough spacing to carry moderate current per circuit without crowding the connector face, while the dual-row layout keeps the overall footprint compact for a 14-way connector. One detail that trips up first-time specifiers: contacts are not included.
This plug housing accepts male pin contacts terminated via crimp to the wire. It mates with the corresponding VAL-U-LOK receptacle housing (female socket side) of the same 4.20mm pitch and circuit count. The latch holder on the plug engages the mating half's locking ramp — an audible click confirms full seating. Panel mount ears on the housing allow the connector to be fixed to a panel cutout, which is typical for pass-through harness interfaces where the connector stays on the enclosure wall.
