Barrier Strip, 6 Circuits, 0.375" Pitch
The Molex Beau 38770 387700106 is a 6-circuit barrier terminal block on a 0.375" (9.53 mm) pitch, laid out in 2 rows for a total of 12 wire entries. It is the 6-circuit member of the Beau 38770 series, a family of dual-wall barrier strips built for panel and chassis wiring. The block uses top-entry screw termination with a closed bottom — no pass-through studs — and carries a flange on each end for secure mounting to the enclosure. Rated 15 A at 300 V, it accepts wire from 14 AWG down to 22 AWG.
The 0.375" (9.53 mm) pitch sets the centre-to-centre spacing between adjacent circuits. That is a standard barrier-block pitch — wide enough to keep 300 V creepage without forcing an oversized panel footprint, but tight enough that a 6-circuit block stays compact on the rail or chassis. The 15 A per-circuit rating is the continuous current each screw-clamp position can carry at the rated voltage; derate above the ambient temperature the block sees inside the enclosure. The 14-22 AWG wire range covers most control-circuit and power-distribution conductors; the screw-clamp top termination holds stranded wire securely, though the closed bottom means each wire terminates at the block — no daisy-chain stud below.
The 387700106 sits alongside the 387700107 in the same Beau 38770 series — same 0.375" pitch, same 15 A / 300 V rating, same screw termination and flange mount. The only functional difference is the circuit count: 6 circuits here versus 7 on the 387700107. If your BOM calls for 7 positions, the 387700107 is the direct match; the 387700106 leaves one circuit short. Every other spec — wire gauge, barrier type, mounting, material, plating — is identical between the two.
