Overview
The SBT12VMCFPPC is a piezoelectric buzzer manufactured by Mallory Sonalert Products Inc. It features internal drive circuitry and operates on DC input within a voltage range of 9 to 12V. The device produces a sound pressure level of 100dB at a distance of 10cm, with a frequency of 1kHz. It utilizes screw terminal connections for power and signal interface. The unit is designed for panel mounting applications and functions reliably within an operating temperature range of -30°C to +65°C.
Feature Summary
- Integrates internal drive circuitry for direct connection to control signals
- Provides high-intensity acoustic output suitable for industrial alerting
- Utilizes durable screw terminal connections for secure electrical interfacing
Applications
- Industrial machinery status indication
- HVAC system fault alarms
- Commercial appliance operational alerts
Procurement Notes
Verify the specific suffix configuration against the official Mallory Sonalert datasheet to ensure compatibility with required mounting hardware and terminal types. Confirm that the 9-12V DC input aligns with the target system power supply. Check for RoHS compliance documentation if environmental regulations apply to the deployment region.
Selection Notes
Select this component when a robust, internally driven piezoelectric alarm is required for panel-mounted installations. Ensure the enclosure allows for adequate sound projection given the 100dB output specification. Verify that the screw terminal interface matches the available wiring harness or PCB layout constraints of the host equipment.
Part Context
This part belongs to the SBT series of industrial buzzers from Mallory Sonalert. The series is characterized by high reliability and resistance to harsh environments. The SBT12VMCFPPC variant specifically denotes the voltage rating, case style, and terminal configuration within this product line.
Replacement Considerations
