Caution in use

9-1 (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 migration.

3)

Please do not use this ultrasonic transducer in water.

4)

Please do not apply an excessive mechanical shock or force on the top of this ultrasonic

transducer and terminal pins. It may cause of disconnection and malfunction.

5)

Please do not use nor storage this ultrasonic transducer in heavy dust condition. It may be

a cause of clogging and low performance. Also, please do not use this transducer in high

humidity or high concentrated exhaust gas. It may be a cause of corrosion and

malfunction.

6)

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 be corroded and

became malfunction.

7)

This transducer does not have a definition of terminal polarity. Please check a signal

before using if you need a signal phase control for your application.

9-2 (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)

Store the products where the temperature and relative humidity do not exceed -10 to 40

degC, and 30 to 80 %RH. Use the products within 6 months after receiving.

9-3 (Notice in mounting)

1)

Please do not apply excessive force to terminals, when soldering.

2)

Please use soldering temperature with not exceeds 350 degC, 3 seconds.

3)

Flow soldering is not applicable.

4)

Please do not clean by water and dissolving agent.

5)

This product cannot be used mounted on PCB. Soldering fillet at the bottom of case may

interfere with throughhole of PCB. Please contact products engineering section of Murata if

you will use this product mounted on PCB.
