Overview
The DB Products 29SL3120LFLA is a self-driven piezoelectric buzzer designed for panel mounting applications. It operates within an input voltage range of 1.5 to 20.0 VDC, with a rated voltage of 12 VDC. The device draws a current of 10 mA and produces a single-tone output at a frequency of 2.8 kHz (2800 Hz). Acoustic performance is specified at 96 dB when driven at 12 VDC from a distance of 30 cm. The unit features wire leads for connection and has physical dimensions of 42 mm in diameter and 16 mm in height.
Feature Summary
- Internally driven piezoelectric mechanism generating a single acoustic tone
- Flange-style design intended for secure panel mounting installation
- Wide operating voltage tolerance supporting low to medium DC power supplies
Applications
- Embedded system status indication
- Industrial automation equipment alerts
- Point-of-sale (POS) terminal signaling
Procurement Notes
Verify the specific ordering suffix against manufacturer documentation to confirm lead time and availability constraints. Ensure the required acoustic output level meets application standards before procurement. Confirm that the flange mounting style aligns with the enclosure design specifications.
Selection Notes
Select this component where high sound pressure levels are required from a compact form factor. The wide voltage range allows flexibility in power supply design without requiring complex driver circuits. Verify that the 42 mm diameter fits within the available panel space constraints.
Part Context
DB Products Limited specializes in acoustic components, including buzzers and piezo elements. This model belongs to their line of internally driven devices, which integrate the driving circuitry directly into the transducer assembly for simplified integration into electronic systems.
Replacement Considerations
No public substitute part numbers are confirmed for this specific model. Replacement requires matching the 42 mm diameter, 16 mm height, and 96 dB acoustic output specifications.
