Overview
The SBT12DLMSPPC is an internally driven piezoelectric transducer manufactured by Mallory Sonalert Products Inc. Designed for audible alert applications, this component operates on a 12VDC supply and features integrated circuitry to generate specific audio patterns. It is engineered for panel mounting with a diameter of approximately 45mm. The device supports low priority or medium priority slow pulse modes, as well as drug or fluid delivery melodies, making it suitable for medical and industrial equipment requiring distinct auditory signals.
Feature Summary
- Internally driven piezoelectric design with integrated control circuitry
- Capable of generating specific melodies such as drug or fluid delivery alerts
- Supports configurable output modes including low priority and medium priority slow pulses
Applications
- Medical equipment alarms
- Industrial indicator systems
- Drug or fluid delivery monitoring devices
Procurement Notes
Verify the specific melody configuration and pinout requirements against the official datasheet before integration. Confirm that the 12VDC operating voltage aligns with the target system power supply. Ensure the 45mm mounting dimension fits the designated enclosure space. Check for any updated compliance certifications required for the intended market.
Selection Notes
Select this component when a self-contained audible alarm with predefined medical-style melodies is required. It eliminates the need for external microcontrollers to drive simple alert tones. Consider the physical size constraints due to the 45mm diameter. Evaluate if the internal circuitry meets the specific sound pressure level needs of the application environment.
