50K Ohm Linear (B) Single Gang 24mm Potentiometer – Jaycar RP3516

You need a 50K linear pot that actually sits flush in your PCB and doesn't rattle loose on the panel. This one's built for that. Jaycar's 24mm single-gang pot runs a 6.35mm shaft with a machined flat — drop a knob on it or grub-screw it, your call. The 3/8 32 T.H.D. bush gives you a solid panel fix. Phenolic pin base means it stands up in the board on its own once soldered. Pins take screened cable if the job calls for hard wiring. 0.5W max. Same standardised footprint every time, so your layout doesn't shift between runs
