CHANGED
Changed bullet from “Hydrophobic Filter Protects Sensor Against Dust, Dirt, Water, and
Contaminants ” to “Hydrophobic Filter Protects Sensor Against Dust, Dirt, Contaminants,
and Water Droplets/Condensation ”; deleted “Application Pending” from UL bullet and
safety statement; added text to the Application section: Note that the initial sealing

level of DS1923 achieves IP56. Aging and use conditions can degrade the integrity of
1, 4, 10
the seal over time, so for applications with significant exposure to liquids, sprays, or
other similar environments, it is recommended to place the Hygrochron under a shield
to protect it. (See www.maximintegrated.com/AN4126 ). The hydrophobic filter may not
protect the DS1923 from destruction in the event of full submersion in liquid
