The shrouded four-wall housing with a locking ramp keeps the mating receptacle aligned and latched under vibration — a half-turn loose in a threaded connector is a dropout; here the ramp latch clicks home and stays put.
This header is surface-mount terminated, which saves board space and eliminates the through-hole soldering step.

Surface mount. The header is terminated by solder reflow, not through-hole insertion.
The header has 20 positions loaded in two rows with 3.00 mm row spacing. All positions are loaded. The pinout follows the standard Micro MATE-N-LOK dual-row layout — consult the product drawing for the exact circuit numbering.
The current rating varies by the wire gauge used in the mating receptacle. The header itself is rated for 250 V.
The base product number is 794638. If you need a pin-compatible alternative within the Micro MATE-N-LOK series, confirm the position count, pitch, and SMT footprint match your BOM.
