Buchanan 796683-2 — 2-Position PCB Terminal Block at 5.00 mm Pitch
It uses a rising cage clamp termination — turning the M3 screw draws the clamp up, trapping the wire against the current bar. Rated 17.5 A at 300 V, it handles typical control-power and signal-level distribution inside an enclosure. The green polyamide housing carries the Buchanan series interlocking side feature, letting you key multiple blocks together on the same rail without a separate jumper system.
Wire Range and Termination Torque
The clamp accepts wire from 12 AWG down to 30 AWG — solid or stranded. The specified screw torque is 0.79 Nm (7.0 Lb-In), which gives a documented, repeatable termination for production or field wiring. The brass screw and clamp are both nickel-plated; the contact bar is brass with tin plating, matched to the wire termination environment rather than a high-cycle mating interface.
Board Mounting and Orientation
Through-hole mounting, with the wire entry horizontal to the board — the screw terminals face the board edge, making this a side-entry block.
Comparing Siblings in the Buchanan Series
The closest functional peer is the 796692-4, an 8-position block on a 5.08 mm pitch with two levels of 4 positions each. Both share the 17.5 A / 300 V rating, the same M3 rising cage clamp, and the interlocking side feature. The decision between them comes down to position count and board footprint: the 796683-2 fits a 2-position single-level layout at 5.00 mm pitch; the 796692-4 serves an 8-position, two-level design at 5.08 mm pitch. The 0.08 mm pitch difference is negligible for layout but the level count changes the wiring scheme entirely.
