This is the female half of the Superseal connection — it accepts the tab contacts crimped to the wire and mates with the matching male header.
Does This Housing Include Contacts?
The note on the listing is explicit: contacts are not included. You order the crimp tab terminals separately, typically the Superseal 1.5 mm or 2.8 mm tab depending on the wire gauge and current requirement. This is the standard practice for sealed automotive connectors: the housing and the terminals are separate line items because the wire size and the contact plating (tin vs gold) vary with the application.
Locking Ramp and Field Retention
The free-hanging (in-line) mounting style means this receptacle terminates a wire harness and mates to a panel-mount or in-line header, not to a PCB directly.
