Handling Notice
- Please don't touch the component with the bare hand, because the electrode may be corroded.
- Avoid excessive pulling of the lead wire, as the wire may break or the soldering point may come off.
- The circuit utilizes transistor switching. The circuit constants for the transistor are optimally chosen to maintain stable operation, so please follow them when designing a circuit.
- Magnetic sounders are driven by an input frequency. The given frequency characteristics can be obtained only when applying a 1/2 duty square wave (Vp-p). End-users must be aware that the frequency characteristics may vary significantly when different waveforms (sine wave, square wave, or other waves) are applied.
- When voltages other than the recommended voltage are applied, the frequency characteristics will also change.
- Please maintain a proper distance from strong magnetic fields during storage, transit, and mounting.
Soldering and Mounting
- Please refer to the HYDZ specification if soldering of the component is required.
- Washing of the component is not acceptable, as it is not sealed.
- Please do not cover the hole with tape or other obstacles, as this will produce irregular operation.

Frequently Asked Questions (FAQ)
QWhat is the difference between HYG9040A-03 and HYG9040A-05?
AThe main difference lies in the rated voltage and coil resistance. The HYG9040A-03 operates at a rated voltage of 3 Vp-p with a coil resistance of 16±4Ω, while the HYG9040A-05 operates at 5 Vp-p with a coil resistance of 30±6Ω. Both share the same resonant frequency of 2731 Hz.
QWhat type of input signal is required to drive the HYG9040A magnetic sounder?
AThe HYG9040A must be driven by a 1/2 duty square wave (Vp-p) at the rated frequency. Using other waveforms such as sine waves or full-duty square waves may result in significantly different frequency characteristics and reduced performance.
QWhat is the minimum sound pressure level of the HYG9040A?
AThe minimum sound pressure level is 80 dB, measured at a distance of 10 cm under rated voltage conditions.
QWhat are the operating and storage temperature ranges for the HYG9040A?
AThe HYG9040A can operate within a temperature range of -20°C to +60°C. For storage, the acceptable range is -30°C to +80°C. Operating outside these ranges may affect performance and longevity.
QIs the HYG9040A RoHS compliant?
AYes, the HYG9040A complies with RoHS environmental protection regulations, making it suitable for use in environmentally conscious product designs across various industries.
QCan the HYG9040A be washed after soldering?
ANo, washing of the component is not acceptable as it is not sealed. Additionally, the sound hole must never be covered with tape or any other material, as this will cause irregular operation. Please refer to the HYDZ specification for proper soldering guidelines.
