It uses a rising cage clamp — the screw draws a clamp plate down onto the stripped wire, giving a gas-tight connection across 12-30 AWG conductors. Side interlocking lets you snap multiple blocks together into a continuous strip without losing position spacing. ## Wiring and Torque — What the Screw Spec Means The M3 screw is torqued to 0.79 Nm (7.0 Lb-In). That is a firm pull — enough to cold-flow the wire strands into the cage without stripping the brass threads. The clamp and screw are both brass with nickel plating, so corrosion at the termination point is not a concern in a climate-controlled panel. The rising cage clamp lifts the wire into a V-groove in the housing wall, which means the conductor sees even pressure across its full cross-section — no point loading that would nick fine-stranded 30 AWG. ## Board Layout — Pitch and Orientation At 5.08 mm pitch, each position needs 0.200 inches of board edge. The vertical wire entry (top entry with the board horizontal) means the terminal block sits flush against the PCB surface — the screw axis is perpendicular to the board. Through-hole pins anchor the block; the 9 positions span about 45 mm of board edge. If you are replacing an existing 5.08 mm pitch block, the footprint matches the standard 0.200-inch grid. The single-level layout keeps the assembly height low — no stacking levels above the board.","metaTitle":"1546073-9 Buchanan Terminal Block, 9 Pos, 17.5 A, 300 V","metaDescription":"Buchanan 1546073-9 PCB terminal block, 9 positions, 5.08 mm pitch, 17.5 A, 300 V, rising cage clamp, M3 screw.
