HIH-4602-L Series Humidity Sensors DESCRIPTION HIH-4602-L Series Relative Humidity (RH) sensors are designed to deliver RH sensing in a rugged, low-cost slotted TO-5 can. The laser-trimmed, thermoset polymer capacitive sensing elements have on-chip integrated signal conditioning, helping to reduce product development times. FEATURES • • • • • • • Near linear voltage output vs %RH Laser-trimmed interchangeability Enhanced accuracy, fast response Chemically resistant Stable, low drift performance Built-in static protection TO-5 can POTENTIAL APPLICATIONS • • • • • Refrigeration Drying Meteorology Battery-powered systems OEM (Original Equipment Manufacturer) assemblies HIH-4602-L-CP sensors include a calibration and data printout to allow individually matched downstream electronics and ±3.5 %RH total accuracy. A typical current draw of only 200 µA allows use in batterypowered systems. www.DataSheet4U.com HIH-4602-L Series Table 1.
