19-Position Power Terminal Block for PCB Mount
The 1-796949-9: The screw - rising cage clamp termination accepts 12-30 AWG wire without a crimp tool — field wiring stays simple. The black polyamide (PA66) housing includes an interlocking side feature for ganging multiple blocks side-by-side on a rail or panel.
Torque It, Then Trust It
The M3 screw is torqued to 0.79 Nm (7.0 Lb-In) — that spec is there because a loose joint runs hot. The rising cage clamp pulls the wire tight against the current bar; the brass - nickel plated clamp and screw resist corrosion in industrial cabinet environments. The contact material is brass - tin plated, adequate for the 17.5 A rating at the rated temperature rise. Torque it to spec, then scan it with a thermal camera on first load — the connection should not be the hot spot.
Board Layout and Wiring
At 5.08 mm pitch, the 19 positions span the board edge — plan the keep-out zone around the screw heads for a screwdriver access. The horizontal wire entry keeps the wiring low-profile in an enclosure.
