The Hirose DF22-3S-7.92C(28) is a 3-circuit receptacle housing from the EnerBee DF22 series, built on a wide 0.312" (7.92mm) pitch that puts it in the power-distribution class rather than signal-density territory.
The most important thing about this part is what it does not include: the crimp contacts. Without those, this housing is just an empty shell. The 7.92mm pitch gives you generous creepage and clearance for power-level wiring — think 14-18 AWG stranded wire feeding a motor drive, a DC distribution point, or a battery interconnect inside an enclosure. The single-row, 3-position layout keeps the harness narrow, and the latch lock means it won't vibrate loose on a conveyor line or a pump skid. Mating half is the corresponding EnerBee DF22 pin header — look for the DF22 series male plug housings with the same 7.92mm pitch and 3-position count. The polarizing key on this receptacle ensures you cannot accidentally cross-connect with a different circuit count or keying variant.
The DF22B-3S-7.92C is the nearest functional peer — same 3 positions, same 7.92mm pitch, same free-hanging latch-lock housing, same white nylon body, and it also excludes contacts. The difference is in the base product code suffix: the B-variant is a standard offering without the (28) dash number that may indicate a specific packaging or color variant. For a BOM line, either will fit the same mating header and accept the same crimp terminals, so the choice comes down to availability and the buyer's preferred order code.
The product status is Active and ROHS3 Compliant.
