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 tip) 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 be corroded and result in improper operation.
- Be careful not to drop the piezoelectric buzzer.
Frequently Asked Questions
Q
What is the resonance frequency of the HYR-1440A piezoelectric buzzer?
The HYR-1440A operates at a resonance frequency of 4.0 KHz, which is its optimal operating frequency for maximum sound output performance.
Q
What is the maximum input voltage for the HYR-1440A buzzer?
The maximum input voltage for the HYR-1440A is 30 Vp-p. Supplying any voltage higher than specified may damage the buzzer and affect its performance.
Q
Can the HYR-1440A piezoelectric buzzer be used outdoors?
The HYR-1440A is designed for indoor use only. If outdoor use is required, adequate waterproofing measures must be provided, as moisture exposure will prevent normal operation.
Q
What is the operating temperature range of the HYR-1440A?
The HYR-1440A can operate within a temperature range of -20°C to +70°C. For storage, the acceptable range extends from -30°C to +80°C.
Q
How should I solder the HYR-1440A buzzer terminals correctly?
Solder the buzzer terminals at a maximum of 350°C (80W max.) within 5 seconds using a silver-containing solder. Exceeding this temperature or time may cause damage to the buzzer.
Q
What housing material is used in the HYR-1440A and what is its weight?
The HYR-1440A features a housing made of Black PBT (Polybutylene Terephthalate), a durable engineering thermoplastic. The total weight of the buzzer is approximately 0.7 grams.
