M22BZ-220ACF

Alarms, Buzzers, And Sirens Overview

The M22BZ-220ACF is an externally driven magnetic buzzer manufactured by Moujen, designed for industrial alarm applications. It operates at a rated voltage of 220 V AC with a current consumption of 50 mA and produces a sound pressure level of 80 dB at a distance of 100 cm. The device functions at a frequency of 2.5 kHz and features a panel mount design with screw terminals for secure electrical connection. Its physical dimensions are approximately 29.6 mm in diameter and 53 mm in length, housed in a black casing with an IP65 rating for environmental protection.

Alarms, Buzzers, And Sirens Feature Summary

• Externally driven magnetic transducer mechanism for reliable acoustic output
• Panel mount construction with front termination style using screw terminals
• IP65 rated enclosure providing dust tightness and water jet resistance
• Operates within a temperature range of -25°C to 70°C

Alarms, Buzzers, And Sirens Applications

• Industrial control panels requiring visual and audible status indication
• Machine tool safety alarm systems
• Electrical cabinet warning devices
• Heavy machinery operator interface alerts

Alarms, Buzzers, And Sirens Procurement Notes

Verify the specific suffix 'CF' against official Moujen documentation to confirm terminal type and acoustic characteristics, as variations exist within the M22BZ series. Ensure the input power supply matches the 220 V AC rating precisely to prevent component failure. Confirm that the mounting hole diameter accommodates the 29.6 mm body size and that the installation environment stays within the specified -25°C to 70°C operating temperature range for optimal performance and longevity.

Alarms, Buzzers, And Sirens Selection Notes

Select this model when a high-decibel audible alarm is required for 220 V AC industrial environments. The IP65 rating makes it suitable for harsh conditions where dust and water exposure are concerns. Compare with the M22BZ-220ACS variant if different acoustic pulse patterns or slight temperature range adjustments are needed. Ensure the available space allows for the 53 mm length projection behind the panel surface.

Alarms, Buzzers, And Sirens Part Context

This component belongs to the Moujen M22BZ series of panel-mount buzzers, which are widely used in industrial automation and electrical infrastructure. The series offers various voltage ratings and acoustic outputs to suit different alarm requirements. The M22BZ-220ACF specifically addresses the need for robust, high-volume audible signaling in standard industrial control cabinets and machinery interfaces.

Alarms, Buzzers, And Sirens Replacement Considerations

The M22BZ-220ACS is a related variant within the same series. Verify if differences in tone pattern (e.g., slow vs. fast pulse) or exact operating temperature limits affect the specific application requirements before substitution.
