What the GT13SC-2/1S-HU Is — a 3-Position Housing for F Terminals
The Hirose GT13SC-2/1S-HU is a 3-position housing from the GT13 series, designed to accept F terminals. This is the shell that holds the crimped contacts in place before mating with the corresponding header or receptacle — it is not a terminal or a plug body on its own. The housing is molded in gray Polybutylene Terephthalate (PBT), a standard flame-retardant thermoplastic that holds up to typical industrial and automotive underhood temperatures. The F connector style tells you the keying and interface geometry is specific to the F-variant within the GT13 family, so the mating half must also be F-style.
Terminal Compatibility — What Crimps Into This Housing
This housing is built for F terminals — that is the only contact family the manufacturer lists as compatible. If you are populating a harness, you need the correct F-series crimp terminal (typically a separate Hirose order code) that matches the wire gauge and current rating of your application. The housing itself provides the mechanical retention and polarization; the terminal carries the electrical path. No terminal is included with the housing.
