🔔 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 piezoelectric 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-12055 piezoelectric buzzer?
The HYR-12055 has a resonance frequency of 4.0 ± 0.3 KHz, making it suitable for standard alarm and notification applications that operate in this frequency range.
Q
What is the maximum input voltage for the HYR-12055?
The maximum input voltage is 25 Vp-p. Exceeding this voltage may damage the buzzer or cause it to malfunction. Always ensure the driving signal stays within the specified range.
Q
Can the HYR-12055 piezoelectric buzzer be used outdoors?
The HYR-12055 is designed for indoor use only. If outdoor use is required, adequate waterproofing measures must be applied, as moisture exposure can cause the buzzer to operate abnormally.
Q
What are the operating and storage temperature ranges?
The operating temperature range is -20°C to +70°C, and the storage temperature range is -30°C to +80°C. Using the buzzer outside these ranges may degrade performance or cause permanent damage.
Q
What soldering conditions are recommended for the HYR-12055?
Soldering should be performed at a maximum of 350°C (80W max.) using a soldering iron tip, within 5 seconds, and with a solder that contains silver to ensure a reliable connection without damaging the buzzer.
Q
What is the sound output level and housing material of the HYR-12055?
The HYR-12055 produces a sound output of ≥80 dB at 10cm (measured at 4.0KHz Square Wave 12Vp-p). The housing is made of Black PPO material, offering good rigidity and heat resistance for reliable long-term use.
