4-Position Plug Housing, 2.20 mm Pitch — Free-Hanging In-Line
The housing accepts tab-type crimp contacts (sold separately) and locks into the matching receptacle with the series' standard locking ramp. Black PBT insulation handles the -40°C to 100°C operating range, which covers most under-hood and industrial cabinet environments. The single-row layout with four positions is a common choice for sensor power, signal daisy-chains, or low-current actuator circuits where the wire count stays under five.
The crimp termination gives a gas-tight connection when the correct tooling is used, and the free-hanging mount means the assembly floats in the harness rather than being fixed to a panel.
No official second-source cross-reference is on record; the mating receptacle is the matching.025 series 4-position housing with the same locking ramp interface.
