TDK Product Features

TDK’s lineup of products for toner detections consists of the two types below. Magnetic toner density / quantity sensors that detect permeability can be used for detecting factors such as two-component toner density as well as residual quantities and levels of magnetic toners.
There is also a lineup of piezoelectric toner quantity sensors that can detect the residual quantities and levels of toners regardless of magnetism or non-magnetism.
