Features: Use metal wire winding to make a resistor. It can withstand higher power than carbon or porcelain gold film. The potentiometer can be used as voltage divider,rheostat and current controller. Good contact between the center sliding end and the resistor body, smooth rotation. The resistor body of the potentiometer has two fixed ends. By manually adjusting the rotating shaft or the slider and changing the position of the movable contact on the resistor body, the resistance value between the movable contact and any fixed end is changed, thereby changing the magnitude of the voltage and current. High resolution,the resolution of the potentiometer reaches 100%. Specification: Type: WX112 Single Turn Performance: power Resistance value adjustment mode: rotation Change mode of resistance value: X (straight line) Allowed Resistance Error:+-5% Resolution:100% Wattage: 5W Package List: 1*Potentiometer
