TDK Product Features

TDK offers high-accuracy sensing elements achieved by our own polymeric materials and assembled Humidity Sensor products that are extremely simple to apply due to our unique circuit designing technology.
These variable resisting humidity sensing elements are highly sensitive and highly accurate due to TDK’s unique manufacturing technology for polymeric materials. They feature high accuracy at ±5%RH, high accuracy, high sensitivity, compactness, high response and low-hysteresis characteristics.
Assembled Humidity Sensor products are compact products that are extremely simple to use and control as they run with DC power and DC voltage outputs. The screw-on types can be easily mounted onto where detections are to be made.
They feature a wide humidity detection range of 5 to 95(%)RH, high humidity detection precision of ±3%RH to ±7%RH, and low-hysteresis characteristics.
They can be used for a wide variety of applications such as printers, refrigerators (outside the refrigerators and for vegetable compartment humidity management), air conditioners (indoor humidity management), and air conditioning equipment at plant factories.
