Conformity to RoHS Directive  
Humidity Sensors  
CHS Series CHS-XS Type  
Based on TDK’s unique manufacturing technology for polymeric  
materials and precision fabrication technology, these variable  
resistance humidity sensing elements are made by combining spe-  
cially selected, high quality materials to deliver excellent resistance  
against water and various gases.  
This consists of a humidity sensing material, a conductive polymer  
film, applied on an electrode board and provides a wide range of  
impedance variation in response to changes in humidity.  
FEATURES  
SHAPES AND DIMENSIONS  
• Small and responsive.  
7.5 0.5  
4 0.5  
• Minimal variation for excellent detection accuracy.  
• Highly resistant to water and gases.  
• As assembled products, they support a wide range of applica-  
tions that make full use of their features  
APPLICATIONS  
Air conditioners, humidifiers, dehumidifiers, dryers, refrigerators,  
PPC, LBP, etc.

SPECIFICATIONS  
REMINDERS FOR USING THESE PRODUCTS  
• These products were designed to be used only with AC. Never  
use DC because doing so can result in severe damage to the  
product, including the electrolysis and peeling of the humidity  
sensing material.

• Please note that even when AC is used, the product will sustain  
the same type of damage as when DC is used if residual DC  
components or asymmetrical waveforms are present.  
• The operational lifetime of these products can be shortened dra-  
matically depending on the operating conditions and storage  
conditions.

If you intend to use these products in any of the types of  
environment listed below, please confirm and estimate their  
operating lifetimes ahead of time:  
(1) Environments in which they are exposed to corrosive gases  
and/or large amounts of dust.  
(2) Environments in which they are exposed to high levels of  
temperature and humidity and/or sudden temperature  
changes.  
(3) Environments in which they are exposed to extreme  
condensation and/or direct exposure to water or salt water.  
• Please implement measures to prevent gases from entering the  
sensor, such as jigs for sealing off the sensors, during processes  
in which gases are produced from decomposing flux, for exam-  
ple, during solder flow.  
• Conformity to RoHS Directive: This means that, in conformity with EU Directive 2002/95/EC, lead, cadmium, mercury, hexavalent chromium, and specific  
bromine-based flame retardants, PBB and PBDE, have not been used, except for exempted applications.  
• All specifications are subject to change without notice.
