PB-0927P-01Q

Alarms, Buzzers, And Sirens Overview

The PB-0927P-01Q is a through-hole magnetic buzzer transducer manufactured by Mallory Sonalert Products Inc. It operates at a nominal voltage of 1.5V with a current draw of 75mA. The device generates an acoustic output of 80dB measured at a distance of 10cm and functions at a frequency of 2.731kHz. It features PC pin termination for panel or board mounting.

Alarms, Buzzers, And Sirens Feature Summary

• Externally driven magnetic transducer design
• Through-hole PC pin termination for secure mounting
• Compact cylindrical form factor suitable for space-constrained enclosures

Alarms, Buzzers, And Sirens Applications

• Low-voltage portable electronic devices
• Battery-operated consumer appliances
• Industrial control panels requiring audible alerts

Alarms, Buzzers, And Sirens Procurement Notes

Verify the specific suffix '01Q' against official Mallory Sonalert documentation to confirm exact electrical tolerances and terminal configuration. Ensure the application circuit provides the required 1.5V DC supply and sufficient current capacity of 75mA for reliable operation.

Alarms, Buzzers, And Sirens Selection Notes

Select this component when an externally driven solution is preferred over internal driver buzzers. It is suitable for applications where the driving signal source is already available and a simple, low-cost magnetic transducer is required for basic alerting functions.

Alarms, Buzzers, And Sirens Part Context

This part belongs to the PB series of magnetic transducers from Mallory Sonalert. These components are distinct from piezoelectric models as they rely on electromagnetic principles. The series offers various voltage ratings and sound pressure levels to suit different audio requirements in industrial and commercial equipment.

Alarms, Buzzers, And Sirens Replacement Considerations

Direct substitutes must match the 1.5V rating, 2.731kHz frequency, and 9mm diameter. Verify that replacement units support through-hole PC pin installation and provide comparable acoustic output at the specified measurement distance.
