Notes

■ Precaution for fundamental structure of sensor

Infrared Array Sensor is a thermopile type infrared sensor which detects the amount of infrared rays. Below conditions generally degrade the temperature accuracy.

Carefully check the performance and stability under actual use conditions, and perform temperature corrections when necessary.

(1) When heating elements exist near the mounting position of the sensor.

(2) When the sensor is exposed to cold or hot air.

(3) When the temperature of the sensor body rapidly changes.

(4) When substances (e.g., glasses, acrylics or steams), which hardly transmit a far infrared ray, exist between the sensor and the detected object.

(5) When substances (e.g., foreign substances or water), which hardly transmit a far infrared ray, adhere to the lense of the sensor.

■ Use environment

(1) Temperature: See the specifications

(2) Humidity: 15 % to 85 % R.H. (Avoid freezing and dew condensation)

(3) Atmospheric pressure: 86 to 106 kPa

(4) Vibrations and shocks may damage the sensor, and cause malfunction and performance deterioration. If loads and shocks are applied on the lense, the damaged sensor may cause malfunction and performance deterioration.

(5) The product is not water/splash-proof. Perform water/dust-proofing and dew condensation / freezing countermeasures in accordance with use environment. When dew condensation occurs, responsiveness of heat source detection may delay for several seconds. Be careful to solder migration caused by adhesion of water droplets on solder parts.

(6) Avoid use and storage in the corrosive gas (organic solvent, sulfurous acid and hydrogen sulfide gases) to avoid malfunction and performance deterioration.

(7) Use surge absorbers as applying the external surge voltage may damage the internal circuit.

(8) Malfunction may occur near electric noises from static electricity, lightning, broadcast or amateur radio stations and mobile phones.

(9) The sensor can continuously operate within the range of using ambient temperature (using ambient humidity). However, ensure that humidity is within the range described in the following page as humidity varies according to temperature. 

 Avoid the continuous operation near the operational limit. The temperature range does not guarantee the durability.

Notes

■ Mounting

Use the land of the printed-circuit board on which the sensor is securely fixed. The recommended printed-circuit board is FR4 (thickness 1.6 mm 0.063 inch). When mounting on the deprecated circuit board, carefully check the performance and quality under actual use conditions before use.

(1) A large noise on the power supply may cause malfunction. Place the recommended capacitor near the sensor  (within 20 mm 0.787 inch of the wiring pattern length) between sensor input terminals (VDD-GND) to secure power superimposed noise resistance. Test with the actual machine and reselect the capacitor with optimal capacitance.

(2) Prevent the metal part of other electronic components from contacting with the sensor body as the upper face (where part numbers are imprinted) of the sensor is GND.

■ Soldering

Due to the thermal capacity of the infrared array sensor is low, therefore, take steps to minimize the effects of external heat.

Damage and changes to characteristics may occur due to heat deformation.

(1) Manual soldering

Set the soldering tip from 350 to 400 ℃ (30 - 60 W), and solder within 3 seconds or less. Note that output may be changed 

if the load is applied to the terminals when the soldering carefully clean the tip of soldering iron.

(2) Reflow soldering

・ Solder coating

We recommend the screen solder printing method as the method of cream. Halogen type (Chlorine type, Bromine type , etc.) or other high-activity flux is not recommended as the residue may affect performance or reliability of resistors.

・ Mounting of sensor

Self alignment may not always work as expected, therefore, be carefully the position of the terminals and pattern.

・ The recommended reflow temperature profile

The recommended reflow temperature profile conditions are given below. The temperature of the profile is assumed to be a value measured with the printed wiring board of the product terminal neighborhood. The temperature of PCB near this product terminal at the time of mounting changes depending on PCB design. Therefore, please confirm the temperature of PCB near this product terminal to become the specified temperature profile when this product be mounted on the PCB.

(3) Solder reworking

Finish reworking in one operation for reworking of the solder bridge, use a soldering iron with a flat tip do not add more flux when reworking Refer the conditions of manual soldering to rework.

(4) Coating of PCB

To prevent the insulation of the PC board after soldering, not to place the chemicals on lens of the sensor when coating.

(5) Dividing of PCB

When you cut, fold, or fix with screw the PCB after mounting the sensor, not to stress to the sensor and the soldered parts.

(6) Structure of sensor terminals

The sensor terminals are designed to be exposed, so contact of the terminals with metal shards and the like will cause output errors. Therefore, be careful not to touch the terminals with the metal piece or the hand.

(7) Both-side soldering

When you do the reflow solder to the back of the PC board after the reflow of the sensor, execute fixed processing, or instance, with the adhesive etc.

(8) When handling this product, do not touch it with bare hands. Please wear gloves.

■ Wire connection

Correctly wire as in the connection diagram. Reverse connection may damage the product and degrade the performance. 

Do not use empty terminals. Such use may damage the sensor. For cable wiring, use shield wires with possibly short wiring lengths to prevent the influence of the noise.

■ Cleaning

If the dirt or water droplets is attached to the lens, wipe it with soft cloth. The lens is damaged when strongly rubbed, and causes the characteristic deterioration. Avoid ultrasonic cleaning since this may cause breaks or disconnections in the wiring.

■ Transportation and storage

(1) Extreme vibration and shock during transport will damage the sensor. Handle the outer box and reel with care.

(2) Storage under extreme conditions will cause soldering degradation, external appearance defects, and characteristic deterioration.

The following storage conditions are recommended.

Temperature:0 ℃ to 45 ℃ 32 ℉ to 113 ℉

Humidity:70 %RH

Others:Not storage in places full of corrosive gases such as sea breeze, Cl2, H2S, NH3, SO2, and NOx, minimal dust.

Not storage in places exposed to direct sunlight.

(3) The sensors are sensitive to moisture and come in moisture-proof packages.

 Observe the following cautions when storing.

・ After the moisture-proof package is unsealed, take the sensors out of storage as soon as possible 

(within 1 week, less than 30 ℃, less than 60 %R.H.,)

・ If the sensors are to be left in storage for a considerable period after the moisture-proof package has been unsealed, keep them in another moisture-proof bag containing silica gel (within 3 months at the most).

(4) When using the product stored for a long time, dry the package before reflow work.

・ When mounting with solder, if thermal stress is applied to sensors that have absorbed moisture, the moisture will vaporize, swelling will occur, and the inside of the package will become stressed. This may cause the package surface to blister or crack. Therefore, take caution and observe the soldering conditions.

■ Other handling cautions

(1) To assure reliability, check the sensor under actual loading conditions. Avoid any situation that may adversely affect its performance.

(2) This product may malfunction if dropped on its own before it is installed. Do not use if this happens.

(3) If the sensor get high frequency vibration, it can be cause of breakdown. When the product get impulse like below,  do not use it.

・ Touch to a object made of metal

・ Touch of mutual sensors

(4) Since static charge can damage the sensor, bear in mind the following handling precautions.

・ Plastic containers should not be used to store or transport the sensors since they readily become charged.

・ Store or transport the product in an environment that hinders the occurrence of static electricity (for example, places with 45 % to 60 % humidity) and protect the product using electrically conductive packaging.

・ Implement static electricity prevention measures once the product packaging has been opened.

(5) Do not use this product which has been disassembled or remodeled.
