M22BZ-024DCS

Alarms, Buzzers, And Sirens Overview

The M22BZ-024DCS is a panel-mount magnetic buzzer manufactured by Moujen, designed for alarm and warning signal applications. It operates at a rated voltage of 24V DC with a current consumption of 50mA AC/DC. The device features a resonant frequency of 2.5kHz and produces a sound pressure level of 80dB at 24V measured at 100cm. It utilizes passive driver circuitry requiring external driving signals. The unit has a diameter of 29.6mm with a maximum seated height of 11.10mm and requires a 22.3mm round panel cutout. Operating temperature ranges from -20°C to +65°C.

Alarms, Buzzers, And Sirens Applications

• Industrial alarm systems
• Warning signal notifications
• Equipment status indication

Alarms, Buzzers, And Sirens Procurement Notes

Verify the specific suffix 'S' corresponds to the slow pulse tone variant as documented in official Moujen datasheets. Confirm RoHS3 compliance status if required by project specifications. Ensure the external driver circuit supports the 50mA current requirement at 24V DC. Check that the mounting panel allows for the specified 22.3mm cutout dimension and 29.6mm overall diameter clearance.

Alarms, Buzzers, And Sirens Selection Notes

Select this component when a passive magnetic buzzer with a 24V DC rating is required for panel-mounted installations. The 2.5kHz resonant frequency provides distinct audible alerts suitable for industrial environments. Consider the 80dB SPL output level relative to ambient noise conditions. Verify compatibility with existing control logic capable of generating the necessary drive signals for passive operation.

Alarms, Buzzers, And Sirens Part Context

This part belongs to the Moujen M22BZ series of panel-mount buzzers. The series offers various voltage ratings and tone configurations. The M22BZ-024DCS specifically denotes the 24V DC version with screw terminals. Related variants include different voltage options or tone characteristics within the same physical form factor.

Alarms, Buzzers, And Sirens Replacement Considerations

Direct substitutes must match the 24V DC rating, 29.6mm diameter, and 22.3mm cutout requirements. Verify identical resonant frequency and sound pressure levels for acoustic equivalence. Ensure compatible passive drive interface and operating temperature range.
