HIH-4602-A/C Series
Humidity Sensors
DESCRIPTION
HIH-4602-A/C Series Relative Humidity (RH) sensors combine
both relative humidity and temperature sensing in a TO-5
housing with a hydrophobic sintered stainless steel filter.
The laser-trimmed, thermoset polymer capacitive sensing
elements have on-chip integrated signal conditioning.
The temperature sensor is thermally connected with the RH
sensor making the HIH-4602-A/C often ideal for measuring
dew point and other absolute moisture terms.
FEATURES
• Near linear voltage output vs %RH
• Laser-trimmed interchangeability
• Enhanced accuracy, fast response
www.Da•taSChheeetm4Uic.caollmy resistant
• Stable, low drift performance
• Built-in static protection
• Often ideal for dew point and absolute moisture
measurements
• TO-5 housing
The HIH-4602-A contains an integral thermistor, while the HIH-
4602-C contains an integral precision RTD.
Factory calibration data supplied with each sensor allows
individually matched downstream electronics and ±3.5 %RH
total accuracy.
POTENTIAL APPLICATIONS
• Refrigeration
• Drying
• Meteorology
• Battery-powered systems
• OEM (Original Equipment Manufacturer) assemblies

General Notes:
• Sensor is ratiometric to supply voltage.
• Extended exposure to >90% RH causes a reversible shift of
3% RH.
• Sensor is light sensitive. For best performance, shield sensor
from bright light.
