Overview
The SC628AN-BTR is an industrial-grade piezoelectric buzzer from the Mallory Sonalert SC series. It operates on a voltage rating of 6 to 28 VAC or DC. The device features a slow pulse tone with a frequency of 2.9 kHz and produces a sound pressure level of 80 dBA. Electrical characteristics include a current rating of 30 mA. It utilizes screw terminals for connection and supports panel mounting. The unit has a diameter of 43 mm and weighs approximately 45 g.
Feature Summary
- Piezoelectric construction for reliable audio signaling
- Slow pulse tone output for distinct alerting
- Industrial-grade design suitable for harsh environments
- Screw terminal connections for secure installation
Applications
- Industrial machinery fault indication
- Control panel status alerts
- Safety system warning signals
- Equipment monitoring alarms
Procurement Notes
Verify the specific suffix requirements against official Mallory Sonalert documentation, as variations may exist regarding certification or terminal types. Confirm that the 6-28V AC/DC rating aligns with the target circuit supply. Ensure panel cutout dimensions match the 43 mm diameter specification before ordering.
Selection Notes
Select this model when a slow pulse auditory signal is required for industrial applications. The 80 dBA output provides clear indication without excessive noise pollution. Verify compatibility with existing panel mounting hardware and ensure the screw terminal interface matches the wiring configuration available in the assembly.
Part Context
This component belongs to the Mallory Sonalert SC series, which includes various piezoelectric buzzers designed for industrial use. The series offers multiple tone options and voltage ratings. The SC628AN-BTR specifically addresses needs for slow pulse signaling with standard industrial electrical interfaces.
Replacement Considerations
Check for SC628ANJ or SC628ANPR if different pulse speeds are acceptable. Verify that alternative models maintain the same 43 mm diameter and screw terminal configuration to ensure physical compatibility.
