Product Description

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

Specific Notes:

1. Device is calibrated at 5 Vdc and 25 ºC.

2. Non-condensing environment.

 

General Notes:

• Sensor is ratiometric to supply voltage.

• Extended exposure to >90% RH causes a reversible shift of 3% RH.

• Sensor is light sensitive. For best performance, shield sensor from bright light.
