Question

Can a Capacitive Sensor detect charged objects?

Answer



Yes, but the sensing distance depends on the charged object and the amount of charge. If the object is charged, the electrostatic capacitance will also change when the status of the electrical load is changed, and so stable detection cannot be performed. For stable detection, it is recommended to first ionize the object.
