What This AMPSEAL 16 Receptacle Housing Is
It accepts male pin contacts (not included) terminated via crimp, and mounts to a panel with a lever-lock fastening system that provides positive retention without tools. The black PBT, glass-filled housing carries a Terminal Position Lock (TPA) feature, which acts as a secondary retainer to confirm each contact is fully seated before the connector is mated — a reliability detail that matters on assembly lines and in field service where a partially seated pin can cause intermittent opens.
Where This Connector Is Used
The AMPSEAL 16 series is a TE Connectivity product line built for powertrain, body electronics, and off-highway vehicle interconnects where the operating environment sees temperature swings from -55°C to 125°C. The 28-position count suits multi-circuit harness breakouts — think engine control modules, transmission interfaces, or cab-mounted junction boxes that need a single sealed pass-through. The lever lock and TPA together mean this housing is specified where the mating pair must stay locked under engine vibration and where the assembly process benefits from a positive terminal-seat check before the harness ships.
Key Design Details for the Harness Builder
The crimp termination allows field-repairable harness construction; the TPA slides in after all contacts are loaded and locks them in place. Panel mounting means the housing is fixed to the bulkhead or enclosure wall, and the mating plug brings the cable assembly to it — a common arrangement for engine-bay pass-throughs where the harness side needs to be serviceable without unbolting the housing.
