The snap-in panel mount secures the housing to a cutout, routing the wire bundle away from the board edge — a common arrangement for removable harness sections in control boxes and automotive junction blocks. ## Dual-Row vs Single-Row: Selecting the Right Housing The DF51-4DEP-2C is the 4-circuit, dual-row member of the DF51 plug housing family. Its closest sibling is the DF51-4EP-2C, which also carries 4 circuits but in a single-row arrangement. The dual-row layout of the DF51-4DEP-2C halves the connector length along the panel edge — a meaningful difference when routing multiple harnesses through a tight cutout area. ## RoHS and Production Status","metaTitle":"Hirose DF51-4DEP-2C SignalBee Plug Housing, 4 Pos 2mm","metaDescription":"Hirose DF51-4DEP-2C SignalBee™ DF51 plug housing, 4 circuits, 2.00mm pitch, dual-row, panel mount snap-in, detent lock.
