Pyroelectric Infrared Sensor

Pyroelectric Infrared Sensor developed and supplied to the market by NiCeRa is being used worldwide for manyapplications. For example, light switch control, visitor acknowledgement, security systems and burglar alarm.Utilizing our expertise gained by years of experience, we satisfy marketing needs for high quality and low cost.

This is called Pyroelectric Effect.

When ferroelectrics receive infrared and absorbs the thermal energy, a change occurs in its spontaneouspolarization, and electrical charge will be excited on its surface in proportion to the amount of change.

Test Item Conditions Criteria

High-Temperature High-Humidity Storage Test JIS C7021: B-11 Condition B Temperature : 60 degC Relative Humidity : 95% Store for 1,000 hours

High-Temperature Storage Test Nicera Conditions based on JIS C7021: B-10 Temperature : 100 degC Store for 1,000 hours

Low-Temperature Storage Test NiCeRa Conditions based on JIS C7021: B-12 Temperature : -40 degC Store for 1,000 hours

Temperature Program of Thermostat Bath

Hermetic Seal Immerse in water, 160mmHg, for 1 minute

No visible bubble.

JIS C7201: A-4

200 cycles with the conditions below :

Heat Shock Test

After test, leave sensors at normal temperature for 2 hours, then measure sensitivity and noise. Sensors of which change rate is within +/- 20% from initial measured values are judged as Pass. No significant damage in appearance.
