Overview
The BRT1209L-01 is an externally driven piezoelectric transducer from the Intervox series. It operates on a DC input voltage range of 1 to 3V, with a nominal rating of 1.5V. The device draws a supply current of 30mA and produces a sound pressure level of 85dB at 1.5V measured at 10cm. Its operating frequency is 2.048kHz. The unit features custom wire leads for integration.
Feature Summary
- Externally driven piezoelectric design for audio warning applications
- Low voltage operation suitable for battery-powered equipment
- Custom wire lead configuration for flexible mounting
Applications
- Equipment requiring small and lightweight audio warning devices
- Battery-operated electronic systems
- General purpose audible alarms
Procurement Notes
Verify the specific voltage requirements against your system's power supply, as the device operates within a 1 to 3V range. Confirm that the custom wire leads meet your assembly specifications. Ensure the 85dB sound pressure level at 1.5V is sufficient for the intended acoustic environment. Check for any environmental constraints regarding the operating temperature range if applicable to your deployment scenario.
Selection Notes
Select this component when a low-profile, externally driven piezo transducer is required for audible signaling. It is appropriate for designs needing a specific frequency output around 2.048kHz. Consider the 30mA current draw in relation to your power budget. This model is suitable where standard packaging does not fit, given its custom lead configuration.
Part Context
This part belongs to the Intervox line of electro-acoustic transducers manufactured by ICC. These devices are designed to eliminate arcing and RF noise while providing reliable audio output. The product line includes various customized solutions for alarms and buzzers, adhering to ISO 9002 standards for manufacturing quality.
Replacement Considerations
No direct public substitute part numbers are confirmed for this specific model. Due to the custom wire leads and specific acoustic parameters, alternative components may require mechanical and electrical redesign.
