Voltage sensor EFS series

Surface Potential Sensors are compact, lightweight, and allow stable operations due to their tuning fork structuring that has been optimized for sensing the surface potential of charged drums. Dependence on detection distance and ambient environments are eliminated and high-accuracy potential detections are made possible with TDK’s unique feedback circuit that gives the probe parts the same potential as that measured by the sensor. Compact probes that can be mounted around photosensitive drums. They are used for MFPs (Multi Functional Printers), the sensing of the surface potential of photosensitive drums for printers, and various other devices.
