5V piezoelectric buzzer Φ17*4mm external drive type for remote control

Description:

A piezo buzzer generates sound because of the piezoelectric effect from the piezoelectric ceramic which drives the metallic diaphragm to vibrate. And a passive buzzer emits a tone when a voltage is applied across it. Because it does not have built-in oscillating source, so it will not tweet if DC signals are used; instead, you need to use square waves whose frequency is between 2K and 5K to drive it.

Feature:
• They feature extremely low power consumption in comparison to electromagnetic units.
• Because these buzzers are designed for external excitation, the same part can serve as both a musical tone oscillator and a buzzer.
• They can be used with automated inserters.Moisture-resistant models are also available.

• The lead wire type with both-sided adhesive tape installed easily is prepared.

Application:

• Medical equipment: glucose meter for blood, temperature test instrument, ECG monitor, fetal heart tester, blood glucose meter

• Home appliances: refrigerator, washing machine, computer, air conditioner, telephone, microwave oven, oven, TV set, keychain

• Electronic products: mobile phone, remote control, anti-lost device, POS machine, electronic toy, robot, watch, facial massager, instruments and apparatuses, unmanned aerial vehicle

• Security equipment: warning lights, anti-theft electronic locks, safety equipment and sirens/alarms/car alarm.

Precautions for use:

• Do not apply DC bias to the piezoelectric buzzer; otherwise insulation resistance may become low and affect the performance.

• Do not supply any voltage higher than applicable to the piezo- electric buzzer.

• Do not use the piezoelectric buzzer outdoors. It is designed for indoor use. If the piezoelectric buzzer has to be used outdoors, provide it with waterproofing measures; it will not operate normally if subjected to moisture.

• A piezoelectric ceramic material of approximately 100μm thick is used in the sound generator of the buzzer. Do not press the sound generator through the sound release hole otherwise the ceramic material may break. Do not stack the piezoelectric buzzers without packing.

• Do not apply any mechanical force to the piezoelectric buzzer; otherwise the case may deform and result in improper operation.

• Be sure to solder the buzzer terminal at 350℃ max.(80W max.)(soldering iron trip) within 5 seconds using a solder containing silver.

• Be careful not to drop the piezoelectric buzzer.
