Taiss 3590S-2-502L Rotary Potentiometer 5K ohm Potentiometer 10-Turn Multi Turn Wire Wound Precision,10 Ring Adjustable Resistor Counting Dial Rotary Knob

These are awesome for testing a pot connection just to see how much flexibility you could add to a 100kOhm connection, even if you decide to put a standard 100kOhm pot in the final design of a project. I built a guitar delay pedal using one of these, and the level of control I have over the time of the delay is phenomenal.The added knob helps with figuring out just how many turns into the thing you are. The pot itself gives you about 10-13 turns, and the knob basically goes from 1-100. Some other folks have complained about a lack of precision in the pot itself, but I haven't found that to be a problem with my projects.My only complaint is that they don't seem to offer larger ones—say, 1mOhm. With something like 1mOhm, you could use one of these to decipher just how much variable resistance a project would be most useful; once again, even if you don't use this type of pot in your final product. It also beats using a trim pot, although it does take up quite a bit of space.

I needed to repair a Hewlett Packard powert supply but it had to be accomplished on a budget. This item was a very close match but I had to cut the shaft a little shorter and file a flat spot on it for the knob's set screw to contact. Otherwise it works great.

Electrically accurate within spec. Operation is smooth mechanically as well.

I ordered two units (four potentiometers) and received two packages:The first had a pair of 10k ten-turn panel mount potentiometers with knobs (but NOT the counting knobs which were the only real selling point). At least these pots were decently smoothe and solid feeling (but no counting knobs).The second package contained five PCB mount rotary encoders which on top of everything else were defective (upon disassembly I discovered why all positions were open circuit to one another at all points in its rotation -- no metalized layer on the rotor!).Neither item was what I ordered and the second was worse than useless since curiosity caused me to disassemble it to figure out WTF was wrong with it even though a rotary encoder could in no way be a drop in replacement for a potentiometer.

I bought these so I could wire these in line with my HO alternator to add resistance so it would trick the vehicle/alternator into thinking I need more voltage hence giving me a extra volt which it worked perfectly and my amplifiers love it !!!

The ten turn dial set screw does not engage the too short shaft even with just the nut and washers on it, let alone through any panel. The pot also gave strange ohm readings at one end of travel, (went to zero ohms and back up during last few degrees of rotation).

Works fine lasts a long time.

-The 10 Turn 10K variable resistor works fine and seems well built and took soldering fine. The POT as been in continuous use for 2 weeks.-The included multi turn vernier dial knob (single digit window version with fine serrated knob) is junk. It worked for about 2 cycles then started binding when the window digit advances and finally wouldn’t work @ all.
