Overview
The WERMA USA Inc. model 11906827 is an internally driven magnetic buzzer belonging to the 119 Series of audible signaling devices. It operates on a voltage of 115 VAC or DC with a current draw of 20mA and produces a sound level of 90dB at a distance of 1 meter. The device supports both continuous and pulse emission modes. It features a panel mount design with a connector interface, measuring approximately 43mm in diameter and 48mm in height.
Feature Summary
- Internally driven magnetic technology for reliable operation
- Supports continuous and pulse signal modes
- Panel mount installation with connector connection
Applications
- Industrial alarm systems
- Audible status indication
- Process safety signaling
Procurement Notes
Verify the specific operating voltage requirement (115V AC/DC) against your system's power supply specifications before procurement. Confirm that the mounting hole dimensions and connector type are compatible with your existing panel infrastructure. Ensure the IP30 protection rating meets the environmental requirements of the installation location, as it is not suitable for wet or dusty conditions without additional housing.
Selection Notes
Select this component when a compact, internally driven magnetic buzzer is required for 115V applications. Consider the 90dB output level for environments requiring clear audible alerts. Evaluate the IP30 rating to ensure adequate protection against solid objects larger than 2.5mm. Compare physical dimensions (43mm diameter, 48mm height) against available space constraints in the control panel or enclosure.
Part Context
This part belongs to the WERMA 119 Series of audible signaling devices. The series is designed for industrial applications requiring reliable sound signaling. WERMA products are known for modular signal tower solutions and intelligent system integration, though this specific item is a standalone buzzer unit.
Replacement Considerations
Publicly confirmed substitute part numbers for model 11906827 were not found in the provided source material. Verify compatibility with any alternative components by matching electrical ratings (115V, 20mA), acoustic output (90dB), and mechanical mounting specifications.
