B2NB-B1D-R

Overview

The Autonics B2NB-B1D-R is a magnetic buzzer designed for panel mounting with a maximum thickness of 4mm. It operates on a DC voltage range of 12-24VDC and consumes a maximum power of 1.5W. The device produces a sound pressure level of approximately 88±12dB at 0.1m when powered by 12VDC. It features selectable continuous or intermittent sound output modes. An integrated LED indicator flashes green or red during operation to provide visual status feedback.

Feature Summary

• Selectable continuous and intermittent sound output modes
• Integrated LED indicator providing visual operational status
• Strong bass sound characteristics
• Designed for secure panel mounting

Applications

• Industrial control panels requiring audible alerts
• Machine safety signaling systems
• Equipment status indication units
• Alarm systems in automated environments

Procurement Notes

Verify the specific suffix 'R' indicates the red LED variant if color differentiation is critical for your installation. Confirm that the operating voltage aligns with your system's DC supply, as the unit requires 12-24VDC. Ensure the panel cutout dimensions accommodate the Ø22/25mm housing size. Check local distributor documentation for current availability and lead times, as these factors are subject to change.

Selection Notes

Choose this model when both audible and visual indicators are required simultaneously. The selectable sound type allows adaptation to different noise environments or alert urgency levels. Consider the 1.5W power consumption for circuit design purposes. Verify that the 88dB sound pressure is sufficient for the ambient noise conditions of the intended application site.

Part Context

This component belongs to Autonics' magnetic buzzer series, which emphasizes durability and clear signaling in industrial settings. The B2NB series typically offers robust construction suitable for harsh environments. The inclusion of an LED distinguishes it from basic acoustic-only models, providing enhanced operator awareness through dual sensory feedback mechanisms.

Replacement Considerations

Direct substitutes must match the 12-24VDC input and similar form factor. Verify that any replacement supports both continuous and intermittent modes if flexibility is needed. Ensure the new unit provides comparable sound pressure levels and includes visual indicators if required by the existing system design.
