The Hirose GT13SCH-4/1PP-HU is the 5-position male housing in the GT13 series, molded in gray polybutylene terephthalate (PBT). It is the receptacle side of the GT13 wire-to-wire interconnect system, designed to accept Hirose M-series crimp terminals. This housing is the starting point for a harness assembly — you select the terminal, wire, and mating female housing to complete the connection.
Terminal Fit — What Goes Inside
This housing is specified for use with Hirose M terminals. That means the crimp contacts you need are from the M series — not the GT13 series terminals if a separate line exists. The housing provides the mechanical retention and polarization; the terminal carries the current and wire connection. Confirm the M terminal part number matches your wire gauge before ordering the housing.
