11100055

Overview

The Werma 11100055 is an internally driven electronic buzzer from the 111 Series, designed for continuous or pulsed acoustic signaling. It operates on a 24 V DC supply with a current consumption of 25 mA and produces an 80 dB sound pressure level at 24 V. The device features a black housing constructed from PC/ABS materials and utilizes M22 panel mounting with screw terminals. It functions within a temperature range of -20°C to +50°C.

Feature Summary

• Internally driven electronic buzzer capable of generating continuous tone or acoustic pulse signals
• Compact design utilizing M22 panel mounting interface with screw terminal connections
• Constructed from durable PC/ABS housing materials in a black finish

Applications

• Industrial machine status indication
• Control panel audible alarms
• Process monitoring systems

Procurement Notes

Verify that the application voltage matches the specified 24 V DC requirement. Confirm that the M22 mounting thread aligns with existing panel cutouts. Ensure the required sound output meets the 80 dB specification. Check for necessary certifications such as CE or cULus depending on regional deployment standards.

Selection Notes

Select this model when an internally driven solution is preferred over externally driven buzzers. The M22 mounting standard ensures compatibility with common industrial panel configurations. Consider the 80 dB output level against ambient noise requirements. Verify that the 24 V DC power supply is available in the control circuit.
