11806815

Overview

The WERMA 11806815 is an internally driven magnetic continuous tone buzzer designed for 24 VAC/DC operation. It delivers a sound pressure level of 90 dB at a frequency of 2.4 kHz. The unit features a grey PC/ABS housing with IP30 protection and weighs 43 g. It utilizes built-in mounting via an M28 thread, with a diameter of approximately 43 mm and a depth of 48 mm.

Feature Summary

• Internally driven magnetic piezo technology for continuous tone generation
• Compatible with both AC and DC power supplies at 24 V nominal voltage
• Robust PC/ABS construction with IP30 ingress protection rating

Applications

• Industrial machine status signaling
• Control panel audible alerts
• Factory automation warning systems

Procurement Notes

Verify the specific ordering code 11806815 against official WERMA documentation to confirm the 24 VAC/DC specification and continuous tone type. Ensure the installation environment supports the IP30 rating and M28 mounting requirements. Cross-reference technical datasheets for electrical parameters such as current consumption and acoustic output levels before procurement.

Selection Notes

Select this component when a continuous tone signal is required for 24 V control circuits. The internal drive simplifies integration by eliminating external oscillators. Consider the 90 dB output and 2.4 kHz frequency for audibility in moderate noise environments. Verify physical space constraints against the 43 mm diameter and 48 mm depth dimensions.

Part Context

This device belongs to the WERMA 118 Series of audible signaling devices. It is categorized as an electronic buzzer module intended for industrial applications. The series typically offers various voltage options and mounting configurations to suit different panel installation needs.

Replacement Considerations

Consult official WERMA substitution guides for compatible alternatives. Verify that any replacement matches the 24 VAC/DC input, M28 mounting thread, and acoustic performance specifications.
