M2BJ-B24C

Alarms, Buzzers, And Sirens Overview

The Omron M2BJ-B24C is a self-drive piezoelectric buzzer from the M2BJ-B series, designed for industrial audio indication. It operates on a rated voltage of 24 VAC or 24 VDC with a current draw of 7 mA. The unit produces a continuous tone at a frequency of 2 kHz and achieves a sound pressure level of 80 dB. It features solder lug terminals for connection and supports panel mounting. The device has an IP40 rating and measures 24 mm x 18 mm x 38 mm.

Alarms, Buzzers, And Sirens Feature Summary

• Self-drive piezoelectric design eliminates the need for external oscillators
• Capable of generating continuous acoustic signals for status indication
• Robust construction suitable for industrial control panel environments

Alarms, Buzzers, And Sirens Applications

• Industrial machinery status signaling
• Control panel audio alerts
• Safety system auditory warnings

Alarms, Buzzers, And Sirens Procurement Notes

Verify the specific suffix against official Omron documentation to confirm the exact sound pattern configuration, as variations exist within the M2BJ-B series. Ensure the operating voltage matches the 24 VAC/DC rating. Confirm that the solder lug termination style is compatible with the assembly process and that the IP40 protection level meets the environmental requirements of the installation site.

Alarms, Buzzers, And Sirens Selection Notes

Select this model when a reliable, self-oscillating indicator is required for 24V systems. The 80 dB output provides adequate audibility in moderate noise environments. Consider the physical dimensions and panel cutout requirements during the mechanical design phase. Verify that the continuous tone characteristic aligns with the intended alarm or notification protocol.

Alarms, Buzzers, And Sirens Part Context

This component belongs to the Omron M2BJ-B series of cylindrical body buzzers. The series offers various voltage and sound pattern options to suit different industrial automation needs. The M2BJ-B24C specifically addresses applications requiring a standard volume continuous tone at 24 volts.

Alarms, Buzzers, And Sirens Replacement Considerations

Consult the official Omron M2BJ-B catalog for direct cross-references. Ensure any substitute maintains the 24 VAC/DC rating, 2 kHz frequency, and 80 dB SPL to preserve system functionality.
