What it is and where it sits in the series
The Molex 395443013 is the 13-circuit member of the Eurostyle ESE 39544 single-level terminal block series — a 5.08 mm pitch rising-cage-clamp block designed for through-hole PCB mount in industrial control, automation, and power distribution harness assemblies. The black polyamide housing carries 13 positions per level on a single tier, with horizontal board-entry orientation and screw-driven cage clamps that grip conductors from 12 to 30 AWG without requiring ferruled preparation on the smaller end of the range.
