The Molex 2025693004 is a 4-circuit, single-row plug from the Ultra-Fit 202569 series. It uses a 3.50 mm pitch and terminates via crimp contacts — a free-hanging, in-line connector meant for wire-to-board or wire-to-wire power distribution in tight harness runs. The black PA66 housing carries a latch holder for positive retention, and the glow wire compliance (IEC 60335-1) makes it a natural fit for appliance and HVAC control boards where the connector sits near heating elements.
The 3.50 mm pitch gives creepage for moderate power levels without crowding the wire bundle. The latch holder clicks home and stays under vibration. The -40°C to 120°C operating range covers cold warehouse and motor drive air stream.
Mating and Termination
This plug accepts female socket contacts (sold separately) that are crimped onto the wire — no soldering, no special tooling beyond the standard Molex hand crimper. It mates with the matching Ultra-Fit receptacle header (typically the 202569 series male pin header). The 1-row layout keeps the harness profile low, which helps when routing through a cable tie or conduit.
