11906828

Overview

The WERMA USA Inc. model 11906828 is an internally driven magnetic acoustic buzzer designed for panel mounting. It operates on a 230V AC supply with a current consumption of 20mA and produces a sound level of 90dB at a distance of 1 meter. The device features a frequency of 2.4kHz and utilizes screw terminals for electrical connection. Constructed in grey, it supports continuous or slow pulse signaling modes and functions within an operating temperature range of -20°C to 50°C.

Feature Summary

• Internally driven magnetic design eliminates the need for external drivers
• Provides clear audible status indication via high-decibel output
• Supports both continuous operation and slow pulse signaling modes

Applications

• Industrial machinery fault signaling
• Control panel alarm systems
• Process safety monitoring alerts

Procurement Notes

Verify that the application voltage matches the 230V AC specification exactly. Confirm that the required signal mode (continuous or slow pulse) aligns with operational needs. Ensure the mounting environment accommodates the specified temperature range and that screw terminal connections are compatible with existing wiring infrastructure.

Selection Notes

Select this component when a self-contained audible indicator is required without additional driver electronics. Consider the 90dB output level relative to ambient noise conditions. Evaluate the 230V AC compatibility against available control power supplies before integration into the system design.
