It's the wire-side half of a sealed, latch-locked wire-to-wire or wire-to-board interconnect. The 5.00mm pitch and single-row layout match the corresponding Signal Double Lock header or receptacle — same series, same pitch, same locking ramp. The black polyamide (nylon) glass-filled shell carries a sealed construction, meaning it resists moisture and dust ingress in the mated state — typical for automotive body harnesses, industrial sensors, or outdoor lighting connections where a simple unsealed connector would corrode.
Critical: Contacts Sold Separately
This housing ships empty — no female socket contacts are included. The crimp termination accepts the wire gauge specified for the series; the terminal then locks into the housing cavity with an audible click. Missing this step is the most common reorder trigger on this series.
Sealed Construction and Latch Lock
The 'Sealed' feature and latch-lock fastening make this plug suited for environments where a standard unsealed connector would fail. The latch lock provides a positive mechanical retention — it clicks when fully mated and resists vibration loosening. The sealed housing, when mated with its counterpart, keeps water spray and dust out of the contact interface. This isn't a submersible IP67-rated connector, but it's a step above a basic unsealed housing for damp or dirty locations.
