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.
Principle of Operation

SBAC10-11-GCompensated Single
Detect intrusion from any angle. Human Body DetectorOutputs by rapid change in ambient temperature are also Flame Detectorcancelled by compensating element.
RE200GGeneral-Purpose Dual
This model is designed for low cost solution while keeping Automatic Lighting Switchdetection performance at reasonable level. Security Alarm
Toys
SFG323-671High-Grade Dual
Best choice for human body detector. Security AlarmHighly sensitive to human body while remaining insensitive Air-Conditionerto ambient temperature change, vibration, RFI, white lightnoise etc.
SBG446-671Omni-Directional Quad
Omni directional detection is archieved by unique quad Security Alarmelement configration. Highly sensitive to small movements (For Ceiling Mount Application)
of hands, heads etc. Automatic Lighting Switch
SQG413-612Dual-Output Quad
With two independent dual element signals, cancellation of Security Alarmsignals by small animal is possible. (Without false alarm by small animals)

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.
