EFM-210

Alarms, Buzzers, And Sirens Overview

The EFM-210 is a piezoelectric buzzer manufactured by East Electronics. It operates within a voltage range of 1 to 18V and draws a supply current of 20mA. The device produces a sound pressure level of 85dB at 12V measured at a distance of 10cm, with an operating frequency of 4kHz. It supports continuous operation mode and features a diameter of 15.4mm.

Alarms, Buzzers, And Sirens Feature Summary

• Produces high sensitivity acoustic output suitable for speaker systems
• Designed for through-hole mounting applications
• Operates in continuous mode with low current consumption

Alarms, Buzzers, And Sirens Applications

• General alarm systems
• Buzzer circuits requiring 4kHz tone generation
• Electronic devices needing compact audible indicators

Alarms, Buzzers, And Sirens Procurement Notes

Verify the specific suffix variant (e.g., EFM-290EK) against environmental requirements such as temperature range when sourcing. Confirm datasheet version accuracy as multiple revisions exist. Ensure compatibility with wave soldering processes if sealed construction is required for washable requests.

Alarms, Buzzers, And Sirens Selection Notes

Select this component for applications requiring a 4kHz continuous tone with 85dB SPL at 12V. Consider the 15.4mm diameter for spatial constraints. Evaluate the 1-18V operating range against system power supplies. Verify through-hole package suitability for the target PCB assembly method.

Alarms, Buzzers, And Sirens Part Context

This part belongs to the East Electronics EFM series of piezoelectric buzzers. The series includes variants like EFM-210A and EFM-250D. These components are categorized under alarms, buzzers, and sirens. The EFM-210 specifically denotes a standard through-hole piezo element with defined electrical characteristics.

Alarms, Buzzers, And Sirens Replacement Considerations

EFM-210A is a documented variant within the same product line. Cross-referencing with other manufacturers requires matching the 4kHz frequency, 85dB SPL, and 15.4mm form factor.
