11806828

Overview

The WERMA USA Inc. model 11806828 is an internally driven magnetic electronic buzzer designed for panel mounting with screw terminals. It operates at a voltage of 230 VAC and draws a current of 20 mA. The device produces a continuous tone at a frequency of 2.4 kHz with a sound pressure level of 90 dB measured at 230 V. The unit features a grey housing and includes a protective cap that contributes to its ingress protection rating.

Feature Summary

• Internally driven magnetic technology for reliable acoustic output
• Continuous tone generation capability
• Panel mount installation using screw terminal connections

Applications

• Industrial alarm systems requiring audible warnings
• Machine status indication panels
• Safety interlock signalers

Procurement Notes

Verify the specific ordering code 11806828 against official WERMA documentation to confirm the 230V AC specification and grey color variant. Ensure compatibility with existing panel cutouts and terminal block configurations before procurement. Cross-reference technical datasheets for precise mechanical dimensions and electrical ratings to avoid integration errors.

Selection Notes

Select this component when a high-decibel audible signal is required for 230V AC environments. The internal drive simplifies circuit design by eliminating external drivers. Consider the IP rating provided by the cap for environmental protection needs. Verify that the 90 dB output meets regulatory noise requirements for the intended installation location.

Part Context

This part belongs to the WERMA electromagnetic buzzer series, which provides compact audible signaling solutions. These components are engineered for industrial durability and consistent performance under varying electrical conditions. The series typically offers various voltage options and mounting styles to suit different control panel architectures.

Replacement Considerations

Confirm pinout and voltage compatibility when substituting. Check if alternative models offer similar decibel levels and frequency characteristics. Verify that physical dimensions allow for direct replacement in existing enclosures without modification.
