Terminal Block for Panel Wiring — 9 Positions, 5.00 mm Pitch
The TE Connectivity Buchanan 796689-9 is a 9-position PCB terminal block from the Buchanan series, designed for wire-to-board termination in industrial control panels, power supplies, and building automation equipment. It uses a rising cage clamp mechanism — turning the M3 screw draws a brass plate up against the conductor, clamping solid or stranded wire from 12 AWG down to 30 AWG without damaging the strands. The 0.197" (5.00 mm) pitch is a standard spacing for terminal blocks, matching the footprint of many existing PCB layouts. Rated 17.5 A per position at 300 V, this block handles moderate branch-circuit current — think motor contactor coils, PLC output modules, or distribution busbars inside an enclosure.
35° Wire Exit and Side Interlocking
The wire termination is oriented at 35° (145°) relative to the PCB plane, which routes the conductor away from the board at a shallow angle — useful when the enclosure lid or an adjacent board limits vertical clearance. Each block has an interlocking feature on the side, so multiple 796689-9 units can be snapped together side-by-side to form a longer terminal strip.
Termination and Torque Spec
The M3 screw is brass with nickel plating; the clamp is brass with tin plating. The specified torque is 0.79 Nm (7.0 Lb-In) — overtightening can strip the threads in the PA66 housing, so use a torque screwdriver set to that value. The contact material is brass with tin plating, adequate for the 17.5 A rating in a dry indoor environment. For corrosive atmospheres, consider a gold-plated contact variant if available in the Buchanan series.
