Notice (Handling)
- 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.
- Do not wash the piezoelectric buzzer with solvent or allow gas to enter it while washing; any solvent that enters it may stay inside a long time and damage it.
- 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.
- Do not place any shielding material or the like just in front of the sound release hole of the buzzer; otherwise the sound pressure may vary and result in unstable buzzer operation. Make sure that the buzzer is not affected by a standing wave or the like.
- Be sure to solder the buzzer terminal at 350°C max.(80W max.)(soldering iron trip) within 5 seconds using a solder containing silver.
- Avoid using the piezoelectric buzzer for a long time where any corrosive gas (H2S, etc.) exists; otherwise the parts or sound generator may corroded and result in improper operation.
- Be careful not to drop the piezoelectric buzzer.
Frequently Asked Questions (FAQ)
What is the resonant frequency of the HYR-1708 buzzer?
The resonance frequency of the HYR-1708 piezoelectric buzzer is 4.5±500 KHz using a square wave input.
What is the maximum voltage the HYR-1708 can safely handle?
The maximum input voltage for this buzzer is 16 Vp-p. Applying higher voltages may damage the internal elements.
Can this piezoelectric buzzer be used outdoors?
The HYR-1708 is designed primarily for indoor use. If deployed outdoors, it must be equipped with waterproofing measures, as moisture will interfere with its normal operation.
What are the temperature limits for storing and operating the buzzer?
The operating temperature range is -20℃ to +70℃, and the storage temperature range is -30℃ to +80℃.
What material is used for the buzzer housing?
The housing of the HYR-1708 buzzer is made of Black PBT (Polybutylene Terephthalate), which provides excellent thermal stability and strength.
