10901077

Overview

The WERMA USA Inc. model 10901077 is an internally driven magnetic audible alarm buzzer designed for industrial signaling applications. It operates on a voltage of 115 VAC/VDC with a current draw of 25 mA and consumes 0.73 W of power. The device produces a sound pressure level of 80 dB at a distance of 1 meter, utilizing a pulse tone frequency of 2.1 kHz. It features a 22 mm panel mount design with screw terminals for connection. The housing is constructed from ABS/polycarbonate material in black, offering an IP65 protection rating against dust and water ingress.

Feature Summary

• Internally driven magnetic technology for reliable acoustic signaling
• IP65 rated housing for protection against dust and water jets
• Pulse tone output capability for distinct alert patterns
• Screw terminal termination for secure electrical connections

Applications

• Industrial control panels requiring visual and auditory status indication
• Safety systems needing high-decibel hazard alerts
• Machinery monitoring where background noise requires piercing tones
• Process automation equipment signaling operational faults

Procurement Notes

Verify the specific voltage requirement (115 VAC/VDC) matches your system before procurement. Confirm that the 22 mm mounting hole dimension aligns with existing panel cutouts. Ensure the IP65 rating meets environmental exposure standards for the installation site. Check for cULus and CE compliance requirements relevant to your regional regulations. Validate that the pulse tone configuration satisfies the intended signaling protocol.

Selection Notes

Select this component when a high-intensity 80 dB alert is necessary for personnel safety or process awareness. Choose this model if the operating environment demands robust IP65 protection against contaminants. Opt for this unit when 115 VAC/VDC compatibility is required without external drivers. Consider this option if screw terminal wiring is preferred over plug-in connectors for vibration resistance.

Part Context

This buzzer belongs to the WERMA electronic sounder series, specifically engineered for industrial environments. It complements visual signaling devices by providing clear auditory feedback. The product line emphasizes durability and compliance with international safety standards. It serves as a critical component in comprehensive factory automation and machinery safety architectures.

Replacement Considerations

Direct substitutes must match the 115 VAC/VDC input and 22 mm form factor. Verify that alternative models offer equivalent 80 dB SPL at 1 meter. Ensure replacement units maintain IP65 ratings for environmental sealing. Confirm compatibility with existing screw terminal wiring methods.
