M2BJ-B24A

Alarms, Buzzers, And Sirens Overview

The M2BJ-B24A is a self-drive piezoelectric buzzer from the Omron 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 device produces an intermittent sound at a frequency of 2 kHz and a sound pressure level of 80 dB. It features solder lug terminals for connection and supports panel mounting. The unit has an IP40 protection 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
• Supports both intermittent and continuous sound output modes via jumper configuration
• Robust construction suitable for industrial environments with IP40 ingress protection

Alarms, Buzzers, And Sirens Applications

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

Alarms, Buzzers, And Sirens Procurement Notes

Verify the specific suffix code to confirm the sound mode (intermittent vs. continuous) and jumper direction requirements. Ensure the supply voltage matches the 24 VAC/DC rating. Confirm that the solder lug termination style is compatible with the assembly process. Check for RoHS compliance documentation if required by project specifications.

Alarms, Buzzers, And Sirens Selection Notes

Select this model when a self-oscillating indicator is required for 24V systems. The intermittent tone option provides distinct auditory feedback compared to continuous tones. Consider the 80 dB output level against ambient noise conditions. Verify panel cutout dimensions align with the 24 mm diameter requirement for proper installation.

Alarms, Buzzers, And Sirens Part Context

This component belongs to the M2BJ-B series of cylindrical body buzzers manufactured by Omron Automation and Safety. The series offers various voltage and sound pattern options to suit different industrial signaling needs. The M2BJ-B24A specifically addresses applications requiring 24V operation with an intermittent alert profile.

Alarms, Buzzers, And Sirens Replacement Considerations

Consult official Omron catalogs for direct cross-references within the M2BJ-B series. Verify electrical parameters and physical dimensions before substituting with other brands. No public substitute part numbers are confirmed in available documentation.
