At 3.50 mm pitch, it's a mid-density power connector, not a fine-pitch signal link; the spacing gives enough room for decent current per circuit without wasting board real estate. The natural PA66 housing carries a glow wire compliance rating, which means it meets the self-extinguishing test for appliance-grade safety — relevant for white goods, HVAC, or any assembly where a hot component could fall against the connector.

Termination is crimp — you'll need the matching Ultra-Fit female socket terminal (sourced separately) and a proper hand or automatic tool. The latch holder fastening means the plug clicks onto the header with a positive lock, not just a friction fit; that matters in a vibrating assembly or a harness that gets field-serviced.
