Honeywell HIH-4602-A/C and HIH-4602-L Series Humidity Sensors

Honeywell HIH-4602-A/C and HIH-4602-L Series Humidity Sensors combine relative humidity and temperature sensing in compact TO-5 housings. The HIH-4602-A/C includes a thermistor or RTD for temperature sensing, enabling dew point and absolute moisture measurement, while the HIH-4602-L focuses on robust and cost-effective RH sensing. Both sensors use laser-trimmed polymer capacitive sensing elements with integrated signal conditioning for reliable performance. Factory calibration ensures ±3.5% RH accuracy, with low power consumption making these sensors suitable for battery-operated systems.
