EFM-260R

Alarms, Buzzers, And Sirens Overview

The EFM-260R is a piezoelectric buzzer manufactured by East Electronics, designed for through-hole mounting with a 26mm diameter. It operates within a voltage range of 3 to 24V and draws 15mA of supply current. The device resonates at a frequency of 3kHz and produces a sound pressure level of 85dB when driven at 12V from a distance of 30cm. It supports continuous operation modes and functions reliably across an operating temperature range of -20°C to +70°C.

Alarms, Buzzers, And Sirens Feature Summary

• Piezoelectric technology for reliable acoustic output
• Through-hole package design for standard PCB integration
• Wide voltage operational range supporting 3V to 24V inputs

Alarms, Buzzers, And Sirens Applications

• Industrial control panel signaling
• Home appliance status alerts
• Security system sirens

Alarms, Buzzers, And Sirens Procurement Notes

Verify the specific suffix 'R' against manufacturer documentation to confirm exact mechanical dimensions and terminal configuration. Ensure the selected component matches the required 26mm diameter and through-hole pin spacing for your printed circuit board layout. Confirm that the 3kHz resonant frequency aligns with your audible alert requirements.

Alarms, Buzzers, And Sirens Selection Notes

Select this component if a 26mm diameter piezoelectric buzzer is required for through-hole assembly. The 85dB SPL at 12V provides adequate volume for general industrial or consumer applications. Consider the 3kHz frequency for distinct auditory signaling. Verify that the 15mA current draw fits within your power budget constraints.

Alarms, Buzzers, And Sirens Part Context

This part belongs to the East Electronics EFM series of piezoelectric buzzers. The series includes variants such as the EFM-260, which differs in resonant frequency (3.5kHz) and diameter (23mm). The EFM-260R specifically denotes the 26mm diameter variant with a 3kHz resonance, distinguishing it from smaller or differently tuned models in the same product family.

Alarms, Buzzers, And Sirens Replacement Considerations

The EFM-260 is not a direct replacement due to differing diameter (23mm vs 26mm) and frequency (3.5kHz vs 3kHz). No other public substitute part numbers are confirmed for this specific model.
