Barrier block, 5 circuits, 0.438" pitch — panel-mount power distribution
The Molex 387303105 is a 5-circuit barrier block from the Beau 38730 series, designed for chassis or panel-mounted power distribution where a screw-terminated, solder-turret bottom connection is needed. The 0.438" (11.12 mm) pitch gives enough spacing between terminals for 14-22 AWG wire without crowding the screw heads, and the dual-wall barrier (2 Wall) isolates each circuit from the next — no accidental shorts from a stray strand. The black PBT/polyester housing carries a flange for bolting to the panel, and the zinc clear chromate steel screws resist corrosion in humid conditions.
Active production, ROHS3 — no end-of-life concern
No obsolescence notice or last-time-buy window is on record. For compliance documentation, the ROHS3 status is confirmed; additional UL or IEC listings are not stated in the available data but are typical for this class of barrier block — verify against your specific regulatory requirement at quote time.
Termination and wiring — screw clamp top, solder turret bottom
Top termination is via screw clamp — strip the 14-22 AWG wire, insert under the clamp plate, torque the steel screw (zinc clear chromate finish). The bottom termination is a solder turret, insulated, meaning the turret post is designed for soldered wire or PCB connection, not a screw or crimp. This dual-termination style is common in panel-mount barrier blocks where the field wiring lands on top screws and the internal harness solders to the turrets below. The flange provides two mounting holes for bolting to the chassis or panel.
