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 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-1325L piezoelectric buzzer?
The HYR-1325L operates at a resonance frequency of 4.8 KHz, which is the optimal frequency for achieving its rated sound output performance.
Q
What is the maximum input voltage for the HYR-1325L?
The maximum input voltage is 25 Vp-p. Supplying any voltage higher than this specified value may damage the buzzer and should be strictly avoided.
Q
Can the HYR-1325L piezoelectric buzzer be used outdoors?
The HYR-1325L is designed for indoor use only. If outdoor use is required, adequate waterproofing measures must be applied, as exposure to moisture will prevent normal operation.
Q
What is the operating temperature range of the HYR-1325L?
The HYR-1325L can operate within a temperature range of -20°C to +70°C. For storage, the acceptable range is -30°C to +80°C.
Q
What soldering conditions are recommended for the HYR-1325L?
Soldering should be performed at a maximum temperature of 350°C (max. 80W soldering iron) within 5 seconds, using a solder that contains silver to ensure a reliable connection.
Q
What housing material is used in the HYR-1325L, and what does it weigh?
The HYR-1325L features a housing made of Black PBT (Polybutylene Terephthalate), a durable engineering thermoplastic. The buzzer weighs approximately 0.7 g, making it lightweight and suitable for compact applications.
