GENERAL INFORMATION
HIH-3602-A and HIH-3602-C Relative Hu-
midity (RH) sensors combine both rela-
tive humidity and temperature sensing in
a TO-5 housing with a hydrophobic sin-
tered stainless steel filter
The laser trimmed thermoset polymer ca-
pacitive sensing elements have on-chip
integrated signal conditioning. The tem-
perature sensor is thermally connected
with the RH sensor making the HIH-3602-
A/C ideal for measuring dew point and
other absolute moisture terms. Factory
calibration data supplied with each sen-
sor allows individually matched down-
stream electronics and
±
2% RH total
accuracy.

NIST CALIBRATION
Each HIH-3602-A or HIH-3602-C sensor includes a sensor spe-
cific NIST calibration and data printout. Sensors are not individu-
ally serialized.
RH SENSOR CONSTRUCTION
Sensor construction consists of a planar capacitor with a sec-
ond polymer layer to protect against dirt, dust, oils and other
hazards.
CAUTION
PRODUCT DAMAGE
The inherent design of this component causes it to be sensitive
to electrostatic discharge (ESD). To prevent ESD-induced
damage and/or degradation, take normal ESD precautions
when handling this product.
