The TE Connectivity 177904-1 is a 10-circuit, dual-row plug housing from the Power Double Lock series, pitched at 3.96mm. It is a free-hanging (in-line) connector body that accepts female socket contacts via crimp termination. The natural PA66 insulator carries a latch lock for positive retention when mated with the corresponding header. This housing is designed for wire-to-board power interconnect applications where the 3.96mm pitch balances current capacity against board space — typical in appliances, industrial controls, and automotive interior harnesses where the latch lock resists vibration-induced separation.
Contacts and Mating
Contacts are not included with this housing — they must be ordered separately as female socket crimp terminals designed for the Power Double Lock series. The mating half is a Power Double Lock header (through-hole or right-angle variants) with the same 3.96mm pitch and dual-row layout. The latch lock on the plug engages with a corresponding ramp on the header, providing audible and tactile feedback on full mate. Operating temperature range is -30°C to 105°C, suited for underhood and industrial cabinet environments.
