Jaycar 100K Ohm Linear (B) Single Gang 16mm Potentiometer – 30mm D-Shaft, 0.2W

Replacing a 100K pot in a level control or sensor circuit and the last one you grabbed was the wrong taper? This is the linear B version – steady, predictable resistance change from end to end. Jaycar's 16mm single gang body, 1/4-inch D-shaft milled flat so your existing knob just drops on. Thirty millimetres of shaft means you can trim it for a flush panel mount without a spacer. 0.2W rating keeps things cool under continuous load. Solder it in, calibrate, done
