What This 2-Position 3.81mm Plug Does on the Wire
The 0395172002: This is a 2-position plug with female sockets from the Molex Eurostyle ESE 39517 series, built for wire-to-board termination at 0.150" (3.81mm) pitch. The 8 A per contact at 300 V rating keeps it in the signal-level power distribution range — think control cabinet wiring, sensor/actuator power, or PLC I/O field connections where 2 circuits are all you need. Mating flange on the plug body locks it to the matching header, keeping the pair together under vibration in an industrial panel.
Mates with a male pin header of the same 0.150" (3.81mm) pitch, 2 positions, from the Eurostyle ESE 39517 series — typically the 03951701xx headers. Free hanging (in-line) mounting — no panel cutout needed; the plug floats on the wire and latches onto the header.
Temperature and Environment
Rated -40°C to 115°C operating range, with a UL94 V-0 polyamide housing — the flame rating covers equipment inside an enclosure where the connector is part of the power distribution path.
