Overview
SENSORS February 2020 Surface Potential Sensors EFS series SENSORS Surface Potential Sensors (2/5) Product compatible with RoHS directive Overview of the EFS series FEATURES A new feedback surface voltage sensor that supports the improved image quality color copiers and next generation color printers with a reliability of ±0.
05V or below.
This voltage sensor is constructed using TDK’s unique, high precision, highly stable detection circuit which feeds the detected photosensitive drum surface potential back to the electrical field line control chopper and probe shield cover.
While completely eliminating the effects of the causes of disturbances in the electric field intervening between the photosensitive drum and the detection electrode, it shows extremely stable and precise output performance where the adverse effects of temperature fluctuations and detection distance (probe positioning) are greatly reduced.
A unique optimized structure and circuit design have achieved the world’s smallest class of miniaturization and weight reduction, as well as greater performance in response to market needs.
Extremely stable output performance is maintained for long periods of time through accurate driving made possible with the unique structural design and superelastic alloy chopper consisting of the piezoelectric element with optimized conversion efficiency.
Quick responsiveness to high-speed and high image quality needs.
APPLICATION Surface potential measurements in photosensitive drums for copiers and paper for PPCs as well as applications for laser beam printers and various equipment.
