11906826

Overview

The WERMA USA Inc. model 11906826 is an internally driven magnetic buzzer indicator designed for panel mounting applications. It operates on a DC voltage of 48 V with a current consumption of 20 mA. The device generates an acoustic signal at a frequency of 2.4 kHz, achieving a sound pressure level of 90 dB measured at a distance of 48 inches (100 cm). This component integrates both visual and audible signaling capabilities within a single unit.

Feature Summary

• Combines visual indication with audible alarm functionality in a single compact unit
• Features an internally driven magnetic mechanism for reliable operation
• Designed for direct panel mounting to facilitate integration into control panels

Applications

• Industrial machinery status monitoring
• Control panel alarm systems
• Process safety warning signals

Procurement Notes

Verify the specific operating voltage requirement matches your system's 48 V DC supply before procurement. Confirm that the acoustic output level of 90 dB meets the environmental noise requirements of the installation site. Ensure the panel mounting dimensions are compatible with the available space in the enclosure. Check for any additional certification requirements specific to your industry regulations.

Selection Notes

Select this model when both visual and audible alerts are required from a single point source. The 48 V DC rating makes it suitable for low-voltage industrial control circuits. Consider the 90 dB output level relative to ambient noise conditions. The panel mount design simplifies installation compared to free-standing units. Evaluate if the integrated magnetic driver provides sufficient reliability for your application environment.
