Applications
Items such as phones, clocks, digital goods, toys, office supplies, air conditioners, microwaves, air conditioners, medical equipment, and automatic regulating devices.
Handling Notice
- 1 Because the electrode may be corroded, please avoid touching the component with your bare hands.
- 2 Refrain from tugging lead wire too much as this could damage the wire or cause the solder point to come off.
- 3 Transistor switching is used in the circuits. When designing a circuit, please adhere to the circuit constants for the transistor's weight, which are optimally designed to preserve stability.
- 4 Because magnetic sounders are powered by an input frequency, they can only produce the specified frequency characteristics when a 1/2 duty square wave (Vb-p) is applied. End users need to be aware that applying different waves, such as sine waves, square waves (Vb-p), or other waves, might cause the characteristics of frequency to alter significantly and take on different shapes.
- 5 Applying a different voltage than what is advised will likewise alter the frequency's properties.
- 6 When storing, please maintain the appropriate distance to avoid strong magnetic fields traveling through and atop.
Soldering and Mounting
- 1 If a soldering component is required, please read the HYDZ specification.
- 2 Since the component is not scaled, washing it is not acceptable.
- 3 To avoid erratic operation, please do not cover the hole with tape or other obstructions.
Measuring Circuit and Condition
- Rated Signal is the input signal.
- Signal Generator, or S.G.
- Millammeter, or mA Amp: Microphone Amplifier Assessing the Condenser — A microphone.

- LCR meter or multimeter for resistance and capacitor. Condition of Measuring: 5–35°C, R.H. 45–75%.
- 25 ± 2°C is the judgment condition. R.H. 45–75%.
Frequently Asked Questions (FAQ)
Q
What is the difference between the HYG8530A-3027 and HYG8530A-5037 models?
A
The main differences are in rated voltage and coil resistance. The HYG8530A-3027 operates at a rated voltage of 3 Vp-p with a coil resistance of 16 ± 2 Ω, while the HYG8530A-5037 operates at 5 Vp-p with a coil resistance of 32 ± 4 Ω. Both share the same resonant frequency of 2700 Hz.
Q
What type of input signal is required for proper operation of the HYG8530A series?
A
The HYG8530A series requires a 1/2 duty square wave (Vp-p) input signal at the rated frequency. Applying other waveforms such as sine waves or full square waves (Vb-p) may significantly alter the frequency characteristics and output performance.
Q
What is the operating temperature range for the HYG8530A magnetic sounder?
A
The HYG8530A series can operate within a temperature range of -20°C to +60°C. For storage purposes, the acceptable range is wider, from -30°C to +80°C.
Q
Is the HYG8530A series RoHS compliant?
A
Yes, the HYG8530A series fully complies with RoHS (Restriction of Hazardous Substances) environmental protection regulations, making it suitable for use in environmentally conscious product designs.
Q
What precautions should be taken when handling or soldering the HYG8530A?
A
Avoid touching the component with bare hands to prevent electrode corrosion. Do not tug or pull the lead wire excessively. Washing the component is not acceptable as it is not sealed. Additionally, do not cover the sound hole with tape or any obstruction, as this may cause erratic operation.
Q
What are the typical applications for the HYG8530A magnetic sounder?
A
The HYG8530A is widely used in consumer and industrial electronics including phones, clocks, digital goods, toys, office supplies, air conditioners, microwave ovens, medical equipment, and various automatic regulating devices where an audible alert or signal is required.
