The Hirose GT5A-1PP-HU(70) is a single-position housing from the GT5 series, designed as the insulating shell that holds an M-series crimp terminal in a wire-to-board or wire-to-wire interconnect.
Mating and Terminal Compatibility
This housing is specified for use with M Terminals from the same GT5 series. The housing provides the primary insulation and polarization for the mated pair — the mating half is the corresponding header or receptacle that carries the pin or socket contact. The single-position format means one housing per circuit, so a multi-circuit harness uses multiple GT5A-1PP-HU(70) housings ganged together or arrayed in a multi-position header.
