Barrier Strip for Panel or PCB Termination
The Molex Beau 387206212 is a 12-circuit barrier terminal strip from the Beau 38720 series, built for power distribution and field-wiring termination in industrial control panels, HVAC equipment, and power supplies. It uses a 0.375" (9.53 mm) pitch between terminals, which gives enough spacing for 14-22 AWG wire under the screw clamp without crowding adjacent circuits. The dual-wall barrier design isolates each position side-to-side, reducing the chance of a stray strand bridging two terminals during wiring. Termination is straightforward: top-entry screws clamp the stripped wire, and the bottom connection is a PC pin that solders into a PCB or can be left as a solder-cup for chassis wiring. The flange at each end gives a screw-mount option for panel attachment, supplementing the through-hole PCB pins for mechanical retention in high-vibration environments.
12 Circuits vs. 8 — Same Footprint, More Positions
The 387206212 carries 12 circuits, while the 387206208 in the same series holds 8 circuits at the same 0.375" (9.53 mm) pitch, same 15 A / 300 V rating, and same dual-wall barrier construction. The physical length scales with the circuit count — the 12-position strip is longer by four terminal positions, so the panel cutout or PCB land pattern must be sized accordingly. If the BOM calls for 12 field-wire terminations, the 387206212 is the direct match; the 8-circuit version would leave four wires unterminated or require a second block.
