The Hirose DF62B-4S-2.2C(11) is a 4-position socket housing from the DF62 series, built for wire-to-board or wire-to-wire crimp interconnect.
The 2.20 mm pitch is tight enough to keep the board footprint small, but the dual-row arrangement means the 4 circuits occupy a compact 2x2 layout — not a single row. The row spacing is 2.00 mm, so the overall footprint is roughly 4.40 mm by 2.00 mm before the latch wings. Compared to the 6-position DF62B-6S-2.2C(11), this 4-position housing is the right call when the BOM calls for exactly four circuits; the extra two positions on the 6-way version leave unloaded cavities that can trap debris in dirty environments.
This is a socket housing — it mates with the matching DF62 series pin header (male side). Termination is crimp: you insert the correct female crimp terminal into the cavity, and the housing's internal lance holds it.
The PBT insulation material provides good dielectric strength for the voltage class this series typically sees, and the latch lock gives positive retention without needing a secondary locking clip in most applications.
