Handling Notice
- 1 Please don't touch the component with the bare hand, because electrode maybe corroded.
- 2 Avoid excessive pulling lead wire because wire may break or soldering point may come off.
- 3 The circuits utilizes transistor switching. The circuit constants for heft of the transistor are optimally chosen to maintain stable, so please follow it when you design a circuit.
- 4 Magnetic sounders are driven by an input frequency. The given frequency characteristics can be obtained only when applying 1/2 duty square wave (Vb-p). The end-users must know the facts that the characteristics of frequency may be quite change in different shapes with the applied various waves, like sine wave, square wave (Vb-p) or the other waves.
- 5 When other voltage are applied than recommended one, the characteristics of frequency will be also changed.
- 6 Please keep proper distance for strong magnetic field when you storing, transiting and mounting.
Soldering and Mounting
- 1 Please read of HYDZ specification, if soldering component is needed.
- 2 Washing of the component is not acceptable, because it is not scaled.
- 3 Please do not cover the hole with tape or other obstacles, as this will produce irregular operation.

Frequently Asked Questions (FAQ)
Q
What is the difference between HYG8540A-3027 and HYG8540A-5037?
The main difference lies in their rated voltage and coil resistance. The HYG8540A-3027 operates at a rated voltage of 3Vp-p with a coil resistance of 16 ± 2Ω, while the HYG8540A-5037 operates at 5Vp-p with a coil resistance of 32 ± 4Ω. Both share the same resonant frequency of 2700Hz and sound pressure level specifications.
Q
What type of input signal is required to drive the HYG8540A magnetic sounder?
The HYG8540A magnetic sounder must be driven by a 1/2 duty square wave (Vp-p) at the rated frequency of 2700Hz. Using other waveforms such as sine waves or full-duty square waves will alter the frequency characteristics and may result in reduced performance or irregular operation.
Q
What is the sound pressure level (SPL) output of the HYG8540A?
The HYG8540A delivers a minimum sound pressure level of 86 dB measured at 10 cm distance when driven at its rated voltage. This measurement is performed under standard conditions of 25 ± 2°C and relative humidity of 45~75%.
Q
Is the HYG8540A compliant with RoHS environmental regulations?
Yes, the HYG8540A magnetic sounder is fully compliant with RoHS (Restriction of Hazardous Substances) environmental protection regulations, making it suitable for use in environmentally sensitive applications and markets that require RoHS compliance.
Q
Can the HYG8540A be washed or cleaned after soldering?
No. Washing or cleaning of the HYG8540A component is not acceptable after soldering, as the component is not sealed. Exposure to cleaning solvents or water can damage the internal structure and cause malfunction. Please refer to the HYDZ specification for proper soldering guidelines.
Q
What are the recommended storage and operating temperature ranges for the HYG8540A?
The HYG8540A has an operating temperature range of -20°C to +60°C, making it suitable for a wide range of environmental conditions. For storage, the acceptable temperature range is -30°C to +80°C. Additionally, it should be kept away from strong magnetic fields during storage, transit, and mounting.
