The Hirose GT5-1S-HU(B) is a single-position housing from the GT5 series, designed to accept F terminals. It's the plastic shell that holds the contact — not a terminal or header itself. The housing is keyed, which means it only mates one way, preventing misalignment during harness assembly or field service. The green PBT body gives it a distinct visual ID for routing in multi-wire bundles.
Terminal Compatibility
This housing is specified for use with F terminals from the same GT5 series. If you're building a harness, pair it with the matching crimp terminal — the housing provides the mechanical retention and polarization, while the terminal carries the current. No other terminal family is listed as compatible.
