The housing is white polyamide (PA66) and carries a -25°C to 90°C operating range, suited for industrial control cabinets, automotive interior harnesses, and outdoor equipment that stays dry. ## Position Count vs. the 9-Circuit Sibling The YLP-12V carries 12 circuits across 3 rows. The sibling YLP-09V shares the same 3-row layout and 4.50mm pitch but stops at 9 positions — three per row. If your BOM calls for 12 circuits, the YLP-12V is the match; the 9-position housing leaves three circuits unconnected. Both use the same crimp terminals and latch lock, so the only decision is the circuit count. ## What the Latch Lock Means for Your Harness The latch lock on the YLP-12V locks the plug to the mating receptacle. In a free-hanging harness subject to machine vibration or cable pull, this lock prevents the connector from walking loose.","metaTitle":"JST YLP-12V YL Series Plug Housing, 12 Pos, 4.50mm","metaDescription":"JST YLP-12V YL series plug housing, 12 circuits, 3 rows, 4.50mm pitch.
