Product Description
The HIH-4010/4020/4021 Series Humidity Sensors are designed for high-volume OEM users, offering a near-linear voltage output for direct input to controllers. With low current draw (typical 200 A), they are suitable for battery-operated systems. Tight sensor interchangeability minimizes OEM calibration costs. These sensors provide instrumentation-quality RH sensing in a competitively priced, solderable SIP package. The HIH-4010 is an uncovered sensor, the HIH-4020 is covered, and the HIH-4021 is covered and condensation-resistant. All models feature a thermoset polymer capacitive sensing element with on-chip signal conditioning, offering excellent resistance to wetting, dust, dirt, oils, and common environmental chemicals. Available in two lead spacing configurations and with or without calibration data printouts.
