42311075

Overview

The Werma 42311075 is a combined signaling device featuring an internally driven magnetic buzzer and a flashing red LED light. It operates on 24 V AC/DC with a current consumption of 120 mA. The unit produces a sound level of 92 dB at 24 V and emits a tone at 2.3 kHz. Designed for wall mounting, it has a diameter of 91 mm and a height of 120 mm. The housing provides IP65 protection against dust and water jets.

Feature Summary

• Combines a continuous/pulsing magnetic buzzer with a flashing red LED indicator in a single unit
• Internally driven electronics eliminate the need for external drivers
• Wall mount design with screw terminals for straightforward installation

Applications

• Industrial machinery status indication
• Factory floor safety alarms
• Equipment fault signaling systems

Procurement Notes

Verify that the operating voltage matches the required 24 V AC or DC supply. Confirm that the 92 dB acoustic output meets site noise regulations. Ensure the IP65 rating is sufficient for the specific environmental conditions. Check that the 120 mA current draw is supported by the control circuit power supply capacity.

Selection Notes

Select this model when both visual and audible alerts are required from a single location. The integrated design simplifies wiring compared to separate components. Consider the 91 mm diameter for panel space constraints. Verify compatibility with existing 24 V control systems before procurement.

Part Context

This component belongs to the Werma signaling devices portfolio, which includes various alarm and indicator solutions. It serves as a compact alternative to installing separate buzzers and lights. The product integrates standard industrial signaling functions into a unified housing for efficient deployment.

Replacement Considerations

No public confirmed substitute part numbers are available in the provided documentation. Direct replacement requires matching the 24 V AC/DC voltage, 120 mA current, 92 dB sound pressure, and IP65 protection rating.
