HS1101LF
HS1101LF
Relative Humidity Sensor
SPECIFICATIONS
Lead free component
High reliability and long term stability
Patented solid polymer structure
Suitable for linear voltage or frequency output circuitry
Fast response time and very low temperature
coefficient
Based on a unique capacitive cell, these relative humidity
sensors are designed for high volume, cost sensitive
applications such as office automation, automotive cabin air
control, home appliances, and industrial process control
systems. They are also useful in all applications where humidity
compensation is needed.
FEATURES
Full interchangeability with no calibration
required in standard conditions
Instantaneous desaturation after long periods in
saturation phase
Compatible with automatized assembly
processes, including Pb free wave soldering
and reflow processes (1)
Individual marking for compliance to stringent
traceability requirements
Part may be washed with distilled water
APPLICATIONS
Automotive
Home Appliance
Printer
Meteorology
