The 0.197" (5.00mm) pitch is the standard Buchanan spacing, matching the footprint for a 9-way block on a 45 mm-wide board edge. Blue polyamide (PA66) housing, rated 17.5 A at 300 V.
Wire Range and Termination Capacity
Accepts 12 AWG down to 30 AWG. The rising cage clamp pulls the conductor against the current bar; the clamp and screw are both brass with nickel plating. Torque spec is 0.79 Nm (7.0 Lb-In). The contact material is brass with tin plating.
Ganging Multiple Blocks
The interlocking side feature lets you snap multiple 796681-9 blocks together side-by-side to build a wider terminal strip. No separate jumper bar needed for commoning adjacent positions if you bridge them with wire — the interlock just keeps the assembly aligned on the PCB. Useful when you need 18 or 27 positions from the same pitch and termination style.
