What it is
The Molex 395443007 is the 7-circuit member of the Eurostyle ESE 39544 series — a single-level, 0.200-inch (5.08 mm) pitch terminal block built for through-hole PCB mount in industrial harness and control-panel applications. Rated 15 A per circuit at 300 V, it uses a screw-rising cage clamp that accepts 12–30 AWG solid or stranded wire without requiring a ferrule, and holds it under spring tension against a brass clamp body plated in tin.
How it mounts and orients
Horizontal entry with board means the wire lands from the field side and the clamp body solders through-hole to the PCB — typical for DIN-rail feed-through or面板布线 where the connector sits flush with the enclosure face. The black PA66 (Nylon 6/6) housing carries the temperature and dielectric ratings. No IP sealing is claimed; this is a bare-board entry block, not a sealed panel connector.
