Product Features
- Turns smoothly through the rotation.Without noise.With a nice resistance values.You can easily work it out and remark the dial.Very smooth operation and it is accurate.The dial motion is very smooth and tight.The dial will turn like butter and they have some heft to them.The turn rotary has smooth transition of amount of resistance.
- The knob is tight on the shaft.The knobs are a nice clean look and the pre-soldered wires make layout easy.The plate with the level markings is a nice touch.With hardware and nice serrated knobs with pointer marking on them.
- The knob can be scaled correctly.Good connector,wire length and shaft diameter.Complete with knob and round scale background.Use it for speed control for a VFD.Exact fit to replace the volume adjustment on Christmas lights and sounds of controller.Using it as a DC motor speed control.
- Easy to solder the leads.Their tolerances will not be very different.Voltage is stable,indicative of a quality internal resistor material.The leads are solid and fit breadboard holes very well.Good for use this turn rotary to make a test tool for checking gauges in vehicles.Solder some test leads and simulate the range of the sensor to calibrate the gauge.
- New life for an old treadmill.Used to replace the speed controller on router.Using with a VFD for motor speed control.Use it to replace the speed knob switch on treadmill.You can install this as a speed control knob for a lathe.You don't have to do any custom work to get it to work.Use it as a variable resistor to ground for fuel injection enrichment.
