The Hirose GT13SC-4/1S-HU is a 5-position receptacle housing from the GT13 series, designed to accept F-series crimp terminals for wire-to-board or wire-to-wire interconnects. The gray PBT body provides the mechanical retention and polarization for the terminal system — this is the half that stays on the wire harness, not the board. With 5 positions, it matches a 5-circuit BOM line where the mating header or plug carries the same count.
Terminal Compatibility — What Crimps Into It
This housing is specified for use with F terminals — the crimp contacts that lock into the PBT cavity. The F terminal family is the standard signal/power contact for the GT13 series; the housing's internal geometry (polarisation ribs, latch windows) is cut for that terminal shape. No other terminal type fits without modifying the housing or risking retention failure.
