The Hirose GT5N-2PP-HU is a 2-position housing from the GT5 series, designed as the receptacle half for a wire-to-board or wire-to-wire interconnect using M-series crimp terminals. The gray Polybutylene Terephthalate (PBT) body provides a standard insulator for general-purpose internal harness applications — think control boxes, power supplies, or appliance wiring where the connector lives inside an enclosure.
Mating and Terminal Fit
This housing accepts M-series crimp terminals — the specific part number for the terminal is not listed here, but the 'For Use With/Related Products' field confirms M terminals are the intended contact. The housing itself is a shell; you crimp the terminal onto the wire, insert it into the cavity, and then mate the housing with the corresponding header or plug from the GT5 series. No latch or locking feature is noted in the spec, so this is a friction-lock or interference-fit housing — fine for low-vibration internal connections where the harness isn't subject to constant flex or pull.
