listed in the above
9-2 Fail-safe
Be sure to provide an appropriate fail-safe function on your product to prevent a second damage t
hat may be caused by the abnormal function or the failure of our product.
10. Caution in use
10-1 (Notice in design and usage)
1) The transducer may generate surge voltage by mechanical or thermal shock.
2) Please do not apply D.C.voltage for ultrasonic transducer to avoid depolarization, or silver
migration of electrode on piezoelectric ceramic.
3) Please do not use this ultrasonic sensor in water.
4) Please do not apply an excessve mechanical shock or force on the top of this ultrasonic
transducer and terminal pins. It may cause of disconnection and malfunction.
5) Care should be taken when select the material to hold, or cover backside of transducer. If it
contains sulfur or sulfide, electrode on piezo-electric element may corroded and because of
malfunction.
10-2 (Notice in storage)
1) The products should not be used or stored in a corrosive atmosphere, especially where
chloride gas, sulfide gas, acid, alkali, salt or the like are present. Store the products in the
room where is normal temperature and humidity, and avoid the sunlight, sudden changes in
temperature and humidity. It may cause of failure or malfunction in such conditions.
2) Please do not use and storage this ultrasonic sensor in hevy dust and high humidity condition.
3) Store the products where the temperature and relative humidity do not exceed -10 to 40
degrees centigrade, and 30 to 80%RH. Use the products within 6 months after receiving.
10-3 (Notice in mounting)
1) Please do not clean by water and dissolvent.
