PUI Audio 83 dBA Surface Continuous Internal Magnetic Buzzer Component 3 V dc Min 6.5V dc Max

This magnetic buzzer component provides a Compact audible signalling solution for electronic systems requiring a continuous tone. Designed for surface mounting on PCBs, it delivers a defined sound output and operates across a modest supply range suitable for control and monitoring equipment in industrial contexts.

• Emits a continuous tone at a maximum frequency of 2700 Hz enabling clear alarm signalling
• Produces sound pressure level of 83 dBA for audible alerts in noisy environments
• Accepts supply voltages from 3V to 6.5V DC allowing flexible drive arrangements
• Rated for maximum ambient temperatures up to 85 °C for harsh-condition use
• Surface mount configuration supports automated PCB assembly processes

• Suitable for audible alerts in factory automation control panels
• Ideal for status indication in instrumentation and control modules
• Used with safety and alarm circuits in electrical enclosures
• Can be used for notification tones in mechanical equipment interfaces

The unit includes an internal drive mechanism so an external drive circuit is not required to generate its continuous tone output.

Its low-profile construction and surface-mount design permit Compact PCB layouts and compatibility with SMT placement and reflow processes.

The component conforms to RoHS and REACH chemical and material regulations, limiting certain restricted substances.

It delivers a steady continuous tone rather than intermittent or pulsed sounds, suitable for sustained alert conditions.
