Overview
The SC307N is an industrial-grade piezoelectric buzzer manufactured by Mallory Sonalert. It operates on a continuous tone with a rated voltage range of 3 to 7 VDC. The device produces a sound pressure level between 87 and 97 dBA at a frequency of approximately 2.9 kHz. Designed for panel mounting, it features screw terminals for electrical connection. The unit is RoHS compliant and constructed for rugged industrial environments.
Feature Summary
- Piezoelectric transducer technology for reliable audio indication
- Continuous tone output suitable for steady-state alarms
- Industrial-grade construction for rugged applications
- Screw terminal connections for secure wiring
Applications
- Industrial machinery status indicators
- Control panel alarm systems
- Equipment failure alerts in manufacturing settings
Procurement Notes
Verify the specific suffix against official Mallory Sonalert documentation to confirm exact acoustic and electrical characteristics. Confirm terminal type and mounting requirements match the design. Check current availability status as supply may be restricted. Ensure environmental ratings meet operational needs.
Selection Notes
Select this component when a low-voltage DC continuous audible alert is required. Verify that the 3-7 VDC operating range aligns with the system power supply. Ensure the panel cutout dimensions accommodate the circular form factor. Confirm that screw terminal termination is compatible with the assembly process.
Part Context
This part belongs to the SC series of industrial buzzers from Mallory Sonalert. The series is characterized by robust piezoelectric elements designed for harsh environments. These units typically feature high sound pressure levels and durable housings suitable for permanent installation in industrial equipment.
Replacement Considerations
Consult official Mallory Sonalert substitution guides for verified equivalents. Cross-reference voltage, sound pressure level, and physical dimensions before swapping. Generic replacements may not match the specific acoustic profile or mounting requirements.
