Overview
The BMT1212XH9.5 is an externally driven magnetic buzzer manufactured by BeStar Technologies, Inc. It operates on a nominal voltage of 12 V with a current consumption of 30 mA. The device produces a sound pressure level of 85 dB at 12 V measured from a distance of 10 cm. Its resonant frequency is specified at 2.3 kHz. The component features a 12 mm diameter and utilizes through-hole PC pins for mounting. It supports a voltage range of 8 to 16 V and functions within an operating temperature range of -25 °C to 70 °C.
Feature Summary
- Externally driven magnetic transducer technology
- Through-hole mounting via PC pins
- Active indicator function
Applications
- Electronic equipment status indication
- Alarm systems requiring audible alerts
- Appliance control panels
Procurement Notes
Verify the specific ordering suffix against official BeStar documentation to ensure correct pin configuration and acoustic specifications. Confirm that the required operating voltage aligns with the 8–16 V range. Check for RoHS compliance markings if environmental regulations apply to your assembly process. Ensure mechanical clearance accommodates the 12 mm diameter and through-hole footprint dimensions.
Selection Notes
Select this component when a self-drive active buzzer is not suitable due to external driver constraints or specific waveform requirements. The magnetic technology offers reliable performance in standard industrial environments. Consider the 85 dB output level for applications requiring moderate audibility without excessive power consumption. Verify that the 2.3 kHz frequency matches the desired acoustic profile for user notification.
Part Context
This part belongs to the BMT series of magnetic buzzers from BeStar Technologies, Inc., which specializes in acoustic components. The series includes variants with different voltages and diameters, such as the BMT1205XH9.5 and BMT1612XH14. These components are designed for use as audio indicators in various electronic devices, providing a cost-effective solution for audible signaling needs.
Replacement Considerations
Direct substitutes may include other 12V magnetic buzzers with similar 12mm diameter and through-hole pin configurations. Verify compatibility regarding resonant frequency and sound pressure level before substitution. Cross-reference with BeStar's internal cross-reference lists for confirmed equivalent part numbers.
