6-Circuit Barrier Block at 0.375" Pitch — Screw Clamp Meets Wire-Wrap
The Molex Beau 38711 0387112206 is a 6-circuit barrier terminal block with a 0.375" (9.53 mm) pitch, designed for applications where a screw-clamp field termination needs to connect to a wire-wrap backplane or PCB. The dual-wall barrier gives each terminal pair its own creepage wall — a detail that matters at the 300 V rating when the block lives in an industrial cabinet with condensation cycles. The black PBT insulation carries a -40°C to 100°C operating range, which covers most indoor and outdoor enclosure environments short of direct engine-bay heat. The bottom side terminates via wire-wrap pins, which means the block is through-hole mounted but the connection to the PCB is a wrapped wire post, not a soldered pin. That makes this block a natural fit for a wire-wrap backplane or a test/development board where rework and signal re-routing are frequent. Wire range is 14-22 AWG, which covers common control wiring and power distribution in the 15 A range. The 6 wire entries match the circuit count — one wire per position, no shared terminals. A flange on each end provides a screw-down mounting point to the panel or board, taking mechanical strain off the wire-wrap pins.
The practical current limit depends on wire gauge and ambient temperature. The 0.375" pitch accommodates 14 AWG wire with screw-clamp terminals. Six circuits fit within a standard board-edge length.
