## **FEATURES** 

> **1.** NaPi0n **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** NaPiOn **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.** NaPi0n Small movement ent 1 Gn **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** NaPidn ° **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.

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.

- Note: This is the reference circuit which drives the MP motion sensor.  Install a noise filter for applications requiring enhanced detection reliability and noise withstanding capability. 

Differences in the specifications of electronic components to which the units are connected sometimes affect their correct operation; please check the units’ performance and reliability for each application. 

Panasonic Corporation accepts no responsibility for damages resulting from the use of this circuit. 

## **4. Installation** 

Install the sensor so that people will be entering from the X direction shown below. 

(If persons approch the sensor from the Z direction, detection distance will be shortened.

MP Motion Sensor (AMN2, 3, 4) 

## **NOTES** 

## **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 performance 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. 

## **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. 

(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. 

## **For Cautions for Use.**
