FEATURES
1. pyroelectric sensor modules contain the
   necessary functions in a small package (TO-5). These
   miniature, high-performance infrared human detection
   sensors take the trouble out of circuit design and mounting.

2. Ideal for small-movement detection thanks to quad-type pyroelectric element.
   The quad-type pyroelectric element contained in
   has four receptors. Since the detection zone within the
   detection range is so precise, even small movements can
   be detected.

3. Lenses can be miniaturized because the pyroelectric element is small
   A short focal length is all that’s required even when
   detecting at the same distance, because the size of the
   NaPiOn pyroelectric element is so small. This means that
   high precision is maintained even though the lens is small
   and the sensor itself has been miniaturized.

4. Small temperature differences also detected.
   NaPiOn detects the temperature difference between the
   detection target and its surroundings, and the lowest
   required temperature difference to the background is 4°C
   7.2°F.
   This means that temperature differences can be accurately
   detected not only in winter, when the temperature
   differences are large, but also in summer, when
   temperature differences are slight.

5. Excellent noise resistance (radiation noise, power supply noise)
   The entire NaPiOn circuitry is enclosed in a metal package, which means it has extremely high electromagnetic shielding capabilities. With proven resistance against power supply noise, it is also resistant against power supply superimposed noise.

TYPICAL APPLICATIONS
1. Home appliance market: Air conditioner, air purifier and
   fan heater
2. Construction equipment: lighting, automatic switches
3. Commercial equipment: vending machines, facilities for
   designated smoking areas
4. Anti-crime device market: crime prevention sensor,
   simple anti-crime devices, surveillance cameras
