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.
