Overview
The SC628ANJ is an industrial-grade piezoelectric buzzer from the Mallory Sonalert SC series, designed for panel mounting. It operates on a voltage range of 6 to 28 VAC or DC with a rated voltage of 28 V. The device produces a slow pulse tone at a frequency of 2.9 kHz and draws a current of 30 mA. Its sound pressure level is specified at 80 dBA. The unit features screw terminals for connection and has physical dimensions of approximately 43 mm in diameter.
Feature Summary
- Generates a slow pulse audio signal suitable for distinct alerting applications
- Utilizes internal drive circuitry for direct connection to power sources
- Constructed with piezoelectric technology for reliable industrial operation
Applications
- Industrial machinery status indication
- Control panel alarm signaling
- Equipment fault detection systems
Procurement Notes
Verify the specific suffix ANJ against official Mallory Sonalert documentation to confirm the slow pulse characteristic and 2.9 kHz frequency rating. Ensure the procurement specification matches the required 6-28 V operating range and 30 mA current draw. Confirm that screw terminal termination is compatible with the target assembly design before ordering.
Selection Notes
Select this component when a distinct slow-pulse audible warning is required within the 6-28 VDC or AC operational envelope. The 80 dBA output provides clear indication without excessive noise pollution compared to higher decibel variants. Verify that the panel mount form factor and screw terminal interface align with the enclosure requirements.
Part Context
This part belongs to the SC series of industrial alarms manufactured by Mallory Sonalert Products Inc. The series offers various acoustic outputs and mounting options for robust environmental conditions. The SC628ANJ specifically addresses applications needing a pulsed tone rather than a continuous signal.
Replacement Considerations
Consult official Mallory Sonalter substitution guides for verified equivalents. Cross-referencing requires matching the 2.9 kHz frequency, slow pulse mode, and 28 V rating.
