EFM-260A

Alarms, Buzzers, And Sirens Overview

The EFM-260A is a through-hole piezoelectric buzzer manufactured by East Electronics. It operates within a voltage range of 8 to 36V DC, with a rated voltage of 24V. The device produces a continuous sound at a resonant frequency of 3.5kHz. At 24V and a distance of 30cm, it achieves a sound pressure level of 85dB while drawing a supply current of 12mA. The component features PC pin termination and has a diameter of 23mm. It is designed for an operating temperature range of -40°C to +85°C.

Alarms, Buzzers, And Sirens Feature Summary

• Integrated driver circuitry for direct connection to power sources
• Through-hole mounting with PC pins for secure board attachment
• Wide operating voltage range supporting 8V to 36V DC input

Alarms, Buzzers, And Sirens Applications

• Industrial control panel audible alerts
• Home appliance status indicators
• Security system sirens

Alarms, Buzzers, And Sirens Procurement Notes

Verify the specific suffix or variant against the manufacturer's latest datasheet to ensure compatibility with required voltage and acoustic specifications. Confirm that the through-hole package dimensions match the PCB footprint design. Check for RoHS compliance requirements if applicable to the target market regulations.

Alarms, Buzzers, And Sirens Selection Notes

Select this component when a high-volume, cost-effective audible indicator is needed for standard industrial voltages. The integrated driver simplifies schematic design by removing the need for external oscillators. Ensure the application environment stays within the specified -40°C to +85°C temperature range for reliable operation.

Alarms, Buzzers, And Sirens Part Context

This part belongs to the East Electronics line of alarms, buzzers, and sirens. It is distinct from the E3X series of crystal resonators also listed in search results. The EFM-260A is a complete electromechanical assembly rather than a passive frequency-determining element.

Alarms, Buzzers, And Sirens Replacement Considerations

Cross-reference with other 24V through-hole buzzers from manufacturers like NMB or Pulse Engineering. Verify that replacement parts maintain the same 3.5kHz frequency and 85dB SPL at 30cm to ensure consistent acoustic performance.
