42331075

Overview

The WERMA USA Inc. model 42331075 is an internally driven magnetic buzzer designed for industrial signaling applications. It operates on a 24 V DC supply and draws a current of 70 mA. The device delivers an acoustic output of 100 dB at the rated voltage, ensuring high audibility in noisy environments. It features a panel mount configuration secured by screw terminals for reliable electrical connection. The unit is constructed to withstand typical industrial conditions while providing clear audible alerts.

Feature Summary

• Internally driven magnetic mechanism for consistent acoustic performance
• High sound pressure level of 100 dB for effective area coverage
• Direct panel mounting with screw terminal connections for secure installation

Applications

• Industrial machinery status indication
• Factory floor alarm systems
• Process control audible warnings

Procurement Notes

Verify that the operating environment supports 24 V DC input and that the required acoustic level of 100 dB meets safety standards. Confirm panel cutout dimensions and mounting hardware compatibility before procurement. Ensure the screw terminal type matches existing wiring infrastructure to avoid adaptation issues during installation.

Selection Notes

Select this component when a dedicated audible signal is required rather than a visual indicator. The 24 V DC specification limits usage to low-voltage control circuits. Consider the 100 dB output against ambient noise levels to ensure effectiveness. Verify that the internal drive mechanism suits the continuous or intermittent duty cycle requirements of the application.

Part Context

This part belongs to the Werma range of alarms, buzzers, and sirens. It serves as a standalone audible signaling unit within industrial automation systems. Unlike stack lights, it provides only acoustic feedback. The design focuses on reliability and clarity of warning signals in manufacturing and processing environments.

Replacement Considerations

No specific substitute part numbers are confirmed in public documentation. Replacement requires matching the 24 V DC voltage, 70 mA current draw, 100 dB acoustic output, and panel mount screw terminal interface to maintain system compatibility.
