The TE Connectivity 184042-2 is a single-position sealed plug housing from the SSC series.
Sealed and Vibration-Ready — What the Ratings Mean
The sealed feature means the housing, when mated with the correct receptacle and fitted with the proper seal-crimp terminal, keeps moisture and dust out of the connection — suited for engine compartments, pressure washers, or outdoor junction boxes. The latch holder locks the plug to its mating half so vibration doesn't work the pair loose; on a single-wire line that's the difference between a signal drop and a reliable circuit.
This plug housing accepts a male pin crimp terminal — the exact TE part number for the terminal is not listed here, so confirm the wire gauge and seal requirement from the SSC series application drawing. Mating half is a sealed SSC series receptacle housing with the same position count and latch feature — order the receptacle and terminals separately.
The 184042-2 is listed as Active and RoHS Compliant. The contacts-not-included note means the BOM must include the correct male pin crimp terminal and any required seal.
