What this 4-position plug housing does for your harness build
The 172338-1 is a 4-position, 2-row plug housing from the Mini-Universal MATE-N-LOK series, designed for wire-to-board applications where the contacts are crimped separately and inserted into the housing. The 0.163" (4.14mm) pitch and matching row spacing keep the footprint compact for a dual-row layout. The latch lock fastening secures the mated pair without additional hardware, which helps in moderate-vibration environments inside an enclosure.
The natural polyamide (PA66) housing provides a UL94 V-2 flame rating typical for this series, suitable for equipment inside an enclosure.
