What it is
The Molex 397000902 is the 2-position member of the Eurostyle 39700 series — a DIN-rail-style through-hole terminal block built around a 0.197-inch (5.00 mm) pitch. Brass contacts with tin plating and a steel push-button clamp accept 14–22 AWG without a screwdriver: press the button, insert the wire, release. Rated 10 A per circuit at 300 V in a single-level 2-way layout, with a green PA66/Nylon 6/6 housing spanning -40°C to 105°C.
What the ratings mean
The 5.00 mm pitch is the board-footprint driver — the hole pattern and body width are fixed by the two-position layout, so check your PCB drill and pad finish against this pitch before committing. The 10 A current rating is per circuit at the listed voltage; the tin-plated contact grade is standard for fixed-installation signal and light-power runs rather than high-cycle field mating. The push-button clamp eliminates the torque variability of a rising-cage screw — wire insertion and removal are tool-assisted but tool-free, which matters in panels where repeated field termination occurs. The 300 V rating covers most industrial control-level wiring; confirm it against the actual circuit voltage in your panel before specifying.
