HIH-4602-A/C Series
Humidity Sensors
DESCRIPTION
The HIH-4602-A contains an integral thermistor, while the HIH-
4602-C contains an integral precision RTD.
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.
Factory calibration data supplied with each sensor allows
individually matched downstream electronics and ±±.5 %RH
total accuracy.
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.

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