M22BZ-220ACS

Alarms, Buzzers, And Sirens Overview

The M22BZ-220ACS is an externally driven magnetic buzzer manufactured by Moujen, designed for panel mounting applications. It operates at a rated voltage of 220V AC and draws a current of 50mA. The device produces an acoustic output of 80dB measured at a distance of 100cm from the source. Its operating frequency is specified as 2.5kHz. The unit features a circular form factor with a diameter of approximately 29.6mm to 29.7mm and a length of 53mm. It utilizes screw terminals for electrical connection and is constructed with a black cap or lens.

Alarms, Buzzers, And Sirens Feature Summary

• Panel mount configuration with front access
• Screw terminal termination style
• Black colored cap or lens

Alarms, Buzzers, And Sirens Applications

• Industrial control panels requiring audible status indication
• Alarm systems utilizing standard industrial relay contacts
• Signal towers and automatic control components

Alarms, Buzzers, And Sirens Procurement Notes

Verify the specific datasheet version provided by Moujen or authorized distributors to confirm exact dimensional tolerances and acoustic testing conditions. Ensure that the driving circuitry can supply the required 50mA at 220V AC without exceeding the contact ratings of the controlling relays. Confirm that the panel cutout dimensions align with the 29.6mm diameter specification for proper mechanical fit.

Alarms, Buzzers, And Sirens Selection Notes

Select this component when a high-voltage AC driven buzzer is required for direct integration into existing 220V AC control circuits. The 50mA current draw must be compatible with the switching capacity of the connected relay or controller output. Consider the 80dB sound pressure level for environmental noise requirements and verify that the 29.6mm mounting diameter fits the available panel space constraints.

Alarms, Buzzers, And Sirens Part Context

This part belongs to the Moujen M22 series of signal tower and alarm components, which includes various buzzer and lamp variants. The M22BZ line typically offers different voltage ratings such as 110V AC and 24V DC options. The suffix ACS indicates specific terminal and lens configurations within the broader M22 product family established since 1961.

Alarms, Buzzers, And Sirens Replacement Considerations

Direct substitutes include other models in the M22BZ series with matching voltage ratings, such as M22BZ-110ACS for 110V AC operation. Verify that any replacement maintains the same 29.6mm mounting diameter and screw terminal interface to ensure mechanical compatibility with existing panel cutouts and wiring harnesses.
