TE Buchanan 796681-2 — 2-Position PCB Terminal Block, 5.00 mm Pitch, Side Entry
Rated 17.5 A at 300 V, it accepts wire from 12 AWG down to 30 AWG. The M3 screw takes a specified torque of 0.79 Nm (7.0 lb-in), which is the install target — under-torque risks loose connections under thermal cycling; over-torque can strip the PA66 threads. The blue housing is moulded in polyamide 6/6 (PA66), a material choice that gives good creep resistance at the clamp loads this block sees. Side interlocking features let you snap multiple blocks together on the same PCB without losing the 5.00 mm pitch alignment across the row. Contact and clamp hardware are brass with nickel plating; the contact surface that touches the wire is tin-plated brass.
The block mounts through-hole — the solder posts go into the PCB and are wave-soldered. The rising cage clamp mechanism lifts a brass plate against the wire when the M3 screw is tightened, gripping the conductor between the plate and the current bar. This style handles solid and stranded wire equally well; the nickel-plated brass clamp resists corrosion in humid cabinet environments. The specified torque of 0.79 Nm (7.0 lb-in) is the figure to set your driver to — not a range, not a maximum.
