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.

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.
