Product Specification

Description：

HIH-4602-A/C Series Relative Humidity (RH) sensors combine both relative humidity and temperature sensing in a TO-5 housing with a hydrophobic sintered stainless steel filter.

The laser-trimmed, thermoset polymer capacitive sensing elements have on-chip integrated signal conditioning.

The temperature sensor is thermally connected with the RH sensor making the HIH-4602-A/C often ideal for measuring dew point and other absolute moisture terms.

The HIH-4602-A contains an integral thermistor, while the HIH-4602-C contains an integral precision RTD.

Features：

• Near linear voltage output vs %RH

• Laser-trimmed interchangeability

• Enhanced accuracy, fast response

• Chemically resistant

• Stable, low drift performance

• Built-in static protection

• Often ideal for dew point and absolute moisture measurements

• TO-5 housing

Potential Applications：

• Refrigeration

• Drying

• Meteorology

• Battery-powered systems

• OEM (Original Equipment Manufacturer) assemblies
