LA42DWQ-22 Linear Rotary 22mm Potentiometer , Variable Speed Driver

Description : Great to use as an indicating knob and dial to control a set speed. Turn the pot and the resistance changes. Connect VCC to an outer terminal, GND to the other, and the terminal connection will have a voltage that varies from 0 to VCC depending on the rotation of the pot. Hook the center terminal to an ADC on a microcontroller and get a variable input from the user. Specifications: Wattage: 1/2W. Maximum Voltage: 250V. Variable speed drive resistance range: 0 to 200K ohms Protection level: IP65 Mounting Hole: 22 mm/ 0.87"
