The Molex 387206205 is a 5-circuit barrier strip from the Beau 38720 series, a terminal block family designed for panel and PCB-mount power distribution. It uses a 0.375" (9.53 mm) pitch — wide enough to handle the 300 V rating and accept 14-22 AWG wire without crowding adjacent terminals. The single-row layout with dual barrier walls (2 Wall) keeps each circuit isolated from its neighbour, reducing the chance of a stray conductor bridging two positions during wiring or maintenance. Top termination is via screws (steel, zinc clear chromate finish), and the bottom termination uses PC pins for through-hole soldering to a PCB. The flange on each end allows chassis or panel mounting, giving mechanical support separate from the solder joints.
The Beau 38720 series covers 4, 5, 8, and 12-circuit versions (order codes 387206204, 387206205, 387206208, 387206212) at the same 0.375" pitch, 15 A rating, and flange footprint. The 5-circuit member is the middle option — you step up from the 4-circuit 387206204 when the BOM needs one more position, and down from the 8-circuit 387206208 when you don't need the extra three circuits. The physical length scales with circuit count, but the mounting hole spacing and PC pin pattern are consistent across the series, so swapping between them only changes the number of terminated positions, not the panel cut-out or PCB land pattern.
