Dimensions and Material (Unit: mm)
Notice (Handling)
-
Do not apply DC bias to the piezoelectric buzzer; otherwise insulation resistance may become low and affect 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 required outdoors, provide waterproofing measures to prevent moisture failure.
-
Do not wash the buzzer with solvent or allow gas to enter it during washing, as entrapped solvent can cause long-term damage.
-
The sound generator uses a ∼100µm thick ceramic material. Do not press through the sound release hole to prevent breakage, and do not stack buzzers without packing.
-
Do not apply mechanical force to avoid case deformation and operational defects.
-
Do not place shielding materials directly in front of the sound hole, and ensure it is not affected by standing waves to avoid sound pressure fluctuations.
-
Solder terminals at 350°C max (80W max soldering iron tip) within 5 seconds using silver-containing solder.
-
Avoid prolonged exposure to corrosive gases (such as H2S) to prevent component and sound generator corrosion.
-
Be careful not to drop the piezoelectric buzzer during transit or assembly.
Frequently Asked Questions (FAQ)
What is the resonant frequency and sound pressure level of HYR-1704P?
The HYR-1704P operates at a resonant frequency of 4.0 KHz and generates a sound output of ≥80 dB at a distance of 10 cm with a 5Vp-p square wave.
What is the maximum allowable input voltage?
The maximum input voltage rating for this model is 30 Vp-p. Applying higher voltage may damage the piezoelectric element.
What are the recommended soldering conditions for manual soldering?
Terminal soldering should be completed within 5 seconds at a maximum iron tip temperature of 350°C (80W max) using solder that contains silver.
Can the HYR-1704P buzzer be installed in outdoor equipment?
The buzzer is primarily designed for indoor use. If outdoor application is necessary, appropriate waterproof and moisture-proof protection must be implemented.
What is the operating and storage temperature range?
The operating temperature range is -20°C to +70°C, and the safe storage temperature range is -30°C to +80°C.
What housing material is used for this model?
The housing is made of durable Black PBT engineering plastic, offering high stability with an overall lightweight footprint of 0.7g.
