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 tr oub le out of cir cuit 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
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.
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 circuitry is enc losed 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.

5. Notes regarding the detection zone
The detection zone has the polarity shown in the diagram
on the right.
When targets enter both the + and – zones with the same
timing, the signals are cancelled each other, thus in this
case there is a possibility that the object cannot be detected
at the maximum specified detection distance.

Motion sensors
MP Motion Sensor (AMN2, 3, 4)
NOTES
For Cautions for Use.
1. Checkpoints relating to principle of
operation
MP motion sensors are passive infrared
sensors which detect changes in the
infrared rays. They may fail to detect
successfully if a heat source other than a
human being is detected or if there are
no temperature changes in or movement
of a heat source. Care must generally be
taken in the following cases. The
perf ormance and reliability of the sensors
must be checked out under conditions of
actual use.
1) Cases where a heat source other
than a human being is detected.
(1) When a small animal enters the
detection range.
(2) When the sensor is directly exposed
to sunlight, a vehicle’s headlights, an
incandescent light or some other source
of far infrared rays.
(3) When the temperature inside the
detection range has changed suddenly
due to the entry of cold or warm air from
an air-conditioning or heating unit, water
vapor from a humidifier, etc.
2) Cases where it is difficult to detect
the heat source
(1) When an object made of glass, acrylic
or other subject which far infrared rays
have difficulty passing through is located
between the sensor and what is to be
detected.
(2) When the heat source inside the
detection range hardly moves or when it
moves at high speed; for details on the
movement speed, refer to the section on
the performance ratings.
2. When the detection area becomes
larger
When the difference between the
ambient temperature and body
temperature is large (more than 20°C
68°F), detection may occur in isolated
areas outside the specified detection
range.
3. Other handling cautions
1) Be careful not to allow dust or dirt to
accumulate on the lens as this will
adversely affect the detection sensitivity.
2) The lens is made of a soft material
(polyethylene).
Avoid applying a load or impact since this
will deform or scratch the lens, making
proper operation impossible and causing
a deterioration in its performance.
3) The sensor may be damaged if it is
exposed to static with a voltage
exceeding ±200V. Therefore, do not
touch its terminals directly, and exercise
adequate care in the handling of the
sensor.
4) When the leads are to be soldered,
solder them by hand for less than 3
seconds at a temperature of less than
350°C 662°F at the tip of the soldering
iron. Avoid using a solder bath since this
will causing a deterioration in the
sensor’s performance.
5) Do not attempt to clean the sensor.
Cleaning fluid may enter inside the lens
area causing a deterioration in
performance.
6) When using the sensors with cables, it
is recommended that cables which are
shielded and as short as possible be
used in order to safeguard against the
effects of noise.
