It carries an IP6K9K ingress rating, meaning it withstands high-pressure, high-temperature washdowns — the kind found in engine bays, off-road equipment, and industrial wash-down zones.
The 2-position count and 4.00 mm pitch are the first check against your BOM — the mating header must be a 2-circuit, 4.00 mm pitch male counterpart. The latch lock fastening provides a positive click-on retention, vibration-resistant for automotive and off-highway use. Contacts are not included in this housing — you order the female crimp terminals separately. The crimp termination means you strip, crimp, and insert; no soldering in the harness. The glass-filled PA6 insulation material holds up to the temperature and chemical exposure typical of the IP6K9K environment.
Sealing and Environment
IP6K9K is the defining feature — this housing is sealed against dust ingress and protected against high-pressure, high-temperature water jets. That places it in engine compartments, agricultural machinery, power-wash zones, and anywhere a standard unsealed connector would fail from moisture or debris.
