It may cause overheating, smoke, or fire. • Connect terminals correctly by verifying the pin layout with the specifications diagram or other instructions. Erroneous connections may lead to unexpected operating errors, overheating, smoke, or fire. • For an impotant and serious application in terms of safety, add protection circuit or any other protection method. 4) Devices and equipment used in assembly should also be grounded. 5) When packing printed circuit boards and equipment, avoid using high-polymer materials such as foam styrene, plastic, and other materials which carry an electrostatic charge. 6) When storing or transporting sensor, the environment should not be generated static electricity (for instance, the humidity should be between 45 and 60%), and sensor should be protected using conductive packing materials. 3. Just after supplying voltage, please note that current in the sensor will be not constant until internal circuit stability. 4. Storage The sensors are transparent plastic packages. They are sensitive to moisture and come in moisture-proof packages. Observe the following cautions when storing. 1) After the moisture-proof package is unsealed, take the sensors out of storage as soon as possible (within 1 week 30°C 86°F/60% R.H.). 2) If the devices are to be left in storage for a considerable period after the moisture-proof package has been unsealed, it is recommended to keep them in another moisture-proof bag containing silica gel (within 3 months at the most). 3) Storage under extreme conditions will cause soldering degradation, external appearance defects, and deterioration of the characteristics. The following storage conditions are recommended: • Temperature: 0 to 30°C 32 to 86°F • Humidity: Less than 60% R.H. (Avoid freezing and condensing) • Atomosphere: No harmful gasses such as sulfurous acid gas, minimal dust. *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, please take caution and observe the soldering conditions in the following section. CAUTIONS FOR USE 1. Applying stress that exceeds the absolute maximum rating If the voltage or current value for any of the terminals exceeds the absolute maximum rating, internal elements will deteriorate because of the excessive voltage or current. In extreme cases, wiring may melt, or silicon P/N junctions may be destroyed. Therefore the design should ensure that the absolute maximum ratings will never be exceeded, even momentarily. 2. Deterioration and destruction caused by discharge of static electricity This phenomenon is generally called static electricity destruction. Static electricity generated by various factors flows through the terminal and occurs to destroy internal elements. To prevent problems from static electricity, the following precautions and measures should be taken when using your device. 1) Person handling sensor should wear anti-static clothing and should be grounded through protective resistance of 500 kΩ to 1 MΩ. 2) A conductive metal sheet should be placed over the work table. Measuring instruments and jigs should be grounded. 3) When using soldering irons, either use irons with low leakage current, or ground the tip of the soldering iron. (Use of lowvoltage soldering irons is also recommended.) Panasonic Corporation Automation Controls Business Unit industrial.panasonic.com/ac/e ASCTB242E 201209-T 5. Recommended soldering conditions <SMD/Chip type> 1) Recommended condition (1) IR (Infrared reflow) soldering method T3 T2 T1 t1 t2 T1 = 150 to 180°C 302 to 356°F T2 = 230°C 446°F T3 = 250°C 482°F or less t1 = 60 to 120 s or less t2 = 30 s or less (2) Soldering iron method Tip temperature: 350 to 400°C 662 to 752°F Wattage: 30 to 60 W Soldering time: within 3 s *We don’t recommend soldering iron method for chip type. 2) Do not do flow soldering. <Through-hole type> 1) Recommended condition (1) Double wave soldering method T2 T1 t2 t1 t3 T1 = 120°C 248°F T2 = 260°C 500°F or less t1 = 120 s or less t2+t3= 6 s or less (2) Soldering iron method Tip temperature: 350 to 400°C 662 to 752°F Wattage: 30 to 60 W Soldering time: within 3 s 2) The soldered position on leads should not be closer than 3mm .118inch to the molding resin of this sensor. 6. Notes for mounting 1) Temperature rise in the lead portion is highly dependent on package size. If multiple different packages are mounted on the same board, please check your board beforehand in an actual product, ensuring that the temperature of the solder area of the sensor terminals falls within the temperature conditions of item 5. 2) If the mounting conditions exceed the recommended solder conditions in item 5, resin strength will fall and the mismatching of the heat expansion coefficient of each constituent material will increase markedly, possibly causing cracks in the package, disconnections of bonding wires, and the like. For this reason, please inquire with us about whether this use is possible. 7. Cleaning solvents compatibility We recommend dip cleaning with an organic solvent for removal of solder flux etc. If you cannot avoid using ultrasonic cleansing, please ensure that the following conditions are met, and check beforehand for defects. • Frequency: 27 to 29 kHz • Ultrasonic power: No greater than 0.25W/cm2 • Cleaning time: No longer than 30 s • Cleanser used: Asahiklin AK-225 • Other: Submerge in solvent in order to prevent the PCB and sensors from being contacted directly by the ultrasonic vibrations. 8. Transportation Extreme vibration during transport will warp the lead or damage the sensor. Handle the outer and inner boxes with care. 9. Avoid using the sensor in environments containing excessive amounts of steam, dust, corrosive gas, or where organic solvents are present. 10. Lead forming and cutting of through-hole type 1) Lead forming must be done at normal temperature before soldering 2) The bent and cut position on leads should not be closer than 3mm .118inch to the base of leads. 3) Lead forming and cutting must be done while fixing the base of leads. 4) Avoid mounting with stress at the base of leads. Note: Applies to unit area ultrasonic power for ultrasonic baths. 11.
