Toner fill level measurement

CQ28 and CQ35 capacitive proximity sensors detect the fill level of the toner through the plastic wall. This ensures that the fill level is always within a defined minimum and maximum level. Depending on the material of the toner housing, measurement from above using UP56, UC4, UC12 or UM18 ultrasonic sensors is the ideal solution.
