What it is and where it fits
The Molex 387006104 is the 4-circuit member of the Beau 38700 barrier strip family, rated 15 A per circuit at 300 V with a 0.325-inch (8.26 mm) pitch. Wire entry is screw-top with zinc clear-chromate steel screws; the PCB side terminates via PC pins on 0.325-inch spacing through the board — the pitch and through-hole footprint drive whether it drops into an existing panel layout. The dual-wall barrier construction and flange feature provide physical segregation between circuits and a registered mounting surface on the panel or chassis — the 14–22 AWG wire range covers the lighter end of industrial panel wiring. Operating range is -40°C to 130°C; the black thermoplastic housing and steel screw hardware suit industrial enclosure environments where temperature cycling and mechanical vibration are present.
