The XB5AD912R10K with Potentiometers Head and potentiometer R10K is a two-part device manufactured by Schneider. The XB5AD912R10K is an encoder with a potentiometers head which converts mechanical rotation into electrical signals used for control and positioning purposes. The R10K potentiometer is the rotary control knob associated with the encoder and is responsible for providing adjusting the resistance value of the encoder. The encoder and potentiometer can be used together or independently and are a popular choice for providing precision control and feedback for industrial and commercial automation applications.
