HIH-4030/31 Series Humidity Sensors DESCRIPTION The HIH-4030/4031 Series delivers instrumentation-quality RH Honeywell has expanded our HIH Series to include an SMD (Relative Humidity) sensing performance in a competitively (Surface Mount Device) product line: the new HIH 4030/4031. priced, solderable SMD. The HIH 4030/4031 complements our existing line of non-SMD humidity sensors. SMD packaging on tape and reel allows for The HIH-4030 is a covered integrated circuit humidity sensor. use in high volume, automated pick and place manufacturing, The HIH-4031 is a covered, condensation-resistant, integrated eliminating lead misalignment to printed circuit board through- circuit humidity sensor that is factory-fitted with a hydrophobic hole. filter allowing it to be used in condensing environments including industrial, medical and commercial applications. The HIH-4030/4031 Series Humidity Sensors are designed specifically for high volume OEM (Original Equipment The RH sensor uses a laser trimmed, thermoset polymer Manufacturer) users. capacitive sensing element with on-chip integrated signal conditioning. Direct input to a controller or other device is made possible by this sensor’s near linear voltage output. With a typical current The sensing element's multilayer construction provides draw of only 200 μA, the HIH-4030/4031 Series is often ideally excellent resistance to most application hazards such as suited for low drain, battery operated systems. condensation, dust, dirt, oils and common environmental chemicals. Tight sensor interchangeability reduces or eliminates OEM production calibration costs. Individual sensor calibration data Sample packs are available. See order guide. is available.
