What it is
The Molex 395430002 is the 2-position member of the Eurostyle ESE 39543 series — a side-entry screw-clamp terminal block sized for through-hole PCB mount. The 5.00 mm pitch is the governing dimensional selector for this product family and drives the board footprint and routing density. Rated 10 A per circuit at 300 V, it sits in the signal/control class rather than power class, and the tin-plated brass contacts reflect standard mating-cycle duty rather than high-cycle or precious-metal grade.
Termination and build
The screw-to-leaf-spring with wire guard grips the full conductor cross-section. Torque is set at 0.34 Nm — overtightening risks cracking the PA66 housing in thermal cycling. The horizontal orientation is fixed; account for the z-height budget in through-hole reflow or wave-solder assembly planning. The black PA66 housing is a standard industrial colour marker, not a functional rating difference.
