B6MA-4GLP

Overview

The Autonics B6MA-4GLP is an internally driven electromechanical melody buzzer designed for AC power applications. It operates on a rated voltage range of 110 to 240VAC at 50/60Hz, with a maximum power consumption of 5W. The device features a square body with a diameter of 66mm and provides a sound pressure level of up to 105dB at 0.1m and 95dB at 1m. It includes four selectable sound types: ambulance, police, ringtone, and For Elise. The unit is equipped with a green indicator LED and offers IP65 protection on the front panel.

Feature Summary

• Internally driven electromechanical design requiring no external driver circuitry
• Four distinct melody options including emergency and musical tones
• Integrated green indicator LED for visual status confirmation
• IP65 rated front panel for enhanced environmental protection

Applications

• Emergency warning systems in industrial facilities
• Security alarm signaling for perimeter monitoring
• Telephone-style notification in office or commercial environments
• Musical indication in automated machinery control panels

Procurement Notes

Verify that the operating environment supports the specified 110-240VAC input range. Confirm that the required sound type matches one of the four factory-set melodies (ambulance, police, ringtone, For Elise). Ensure mounting provisions accommodate the 66mm diameter and that the IP65 rating meets the installation site's environmental requirements. Check for compatibility with existing control wiring standards.

Selection Notes

Select this model when an AC-powered, self-contained audible signaler is required without external drivers. Choose based on the need for specific melody outputs rather than continuous tone. Consider the 105dB output capability for noisy environments. Verify that the green LED indicator suffices for visual signaling needs compared to other color options available in the series.

Part Context

This component belongs to the Autonics B6MA series of melody buzzers, which are designed for versatile audible signaling. The series typically includes variants with different voltage ratings and LED colors. The B6MA-4GLP specifically denotes the AC voltage version with green LED illumination, distinguishing it from DC models or those with alternative visual indicators within the same product family.

Replacement Considerations

Direct substitutes must match the 110-240VAC input and 66mm form factor. Verify that replacement units offer comparable sound pressure levels and similar melody options. Ensure the new component maintains equivalent IP65 front panel protection if used in harsh environments. Cross-reference pinouts and mounting hole patterns to ensure mechanical compatibility.
