HIH-4010/4020/4021 series humidity sensors description the HIH-40104020/4021 series humidity sensors are designed specifically for high volume oem (original equipment manufacturer) users. direct input to a controller or other device is made possible by this sensor?s near linear voltage output. with a typical current draw of only 200 a, the HIH-4010/4020/4021 series is often ideally suited for low drain, battery operated systems. tight sensor interchangeability reduces or eliminates oem production calibration costs. individual sensor calibration data is available. the HIH-4010/4020/4021 series delivers instrumentation- quality rh (relative humidity) sensing performance in a competitively priced, solderable sip (single in-line package). the HIH-4010 is an uncovered integrated humidity sensor, the hih-4020 is a covered integrated circuit humidity sensor, and the hih-4021 is a covered, condensation-resistant, integrated circuit humidity sensor. all three products are available in two lead space configurations. the rh sensor is a laser trimmed, thermoset polymer capacitive sensing element with on-chip integrated signal conditioning. the sensing element's multilayer construction provides excellent resistance to most application hazards such as wetting, dust, dirt, oils and common environmental chemicals. both products are available in two lead spacing configurations, as well as with or without calibration and data printouts. features ? molded thermoset plastic housing ? near linear voltage output vs %rh ? laser trimmed interchangeability ? low power design ? enhanced accuracy ? fast response time ? stable, low drift performance ? chemically resistant potential applications ? refrigeration equipment ? hvac (heating, ventilation and air conditioning) equipment ? medical equipment ? drying ? metrology ? battery-powered systems ? oem assemblies
