PT-1340P-P7.6-PQ

Alarms, Buzzers, And Sirens Overview

The PT-1340P-P7.6-PQ is a piezoelectric buzzer manufactured by Mallory Sonalert Products Inc., designed for through-hole mounting with a diameter of 14mm and a height of 7.7mm. It operates at a nominal voltage of 5V and features an externally driven transducer driver circuitry, requiring external components to generate the drive signal. The device produces a sound pressure level of 80 dBA at a frequency of 4kHz (with some sources citing 5.0kHz). It utilizes solder pin termination for secure PCB integration.

Alarms, Buzzers, And Sirens Feature Summary

• Externally driven piezoelectric transducer design
• Compact form factor suitable for space-constrained applications
• Through-hole mounting with solder pin termination
• Dual tone output capability

Alarms, Buzzers, And Sirens Applications

• Electronic equipment status indication
• Alarm systems requiring compact acoustic signaling
• Industrial control panels
• Consumer electronics audio alerts

Alarms, Buzzers, And Sirens Procurement Notes

Verify the specific drive frequency requirement against datasheet specifications, as sources indicate variations between 4kHz and 5kHz. Confirm that the external drive circuitry matches the component's electrical characteristics. Ensure the through-hole footprint aligns with the PCB layout. Check RoHS compliance status if required for the project. Validate the operating voltage range of 5-25VPP for the intended application environment.

Alarms, Buzzers, And Sirens Selection Notes

Select this component when a compact, high-intensity acoustic indicator is needed for through-hole assembly. It is suitable for designs where external driver ICs or oscillators are already present in the circuit. Consider the 80 dBA output level for audible alert requirements. The 14mm diameter allows for easy integration into standard enclosures. Ensure the external drive circuit can handle the specified voltage and current parameters.

Alarms, Buzzers, And Sirens Part Context

This part belongs to the PT series of piezoelectric buzzers from Mallory Sonalert. It is distinct from internally driven models like the STA22702W, as it requires external circuitry for operation. The series offers various sizes and frequencies, with this model focusing on a balance of size and acoustic output for general-purpose signaling.

Alarms, Buzzers, And Sirens Replacement Considerations

No direct public substitute part numbers are confirmed in the provided documentation. Evaluate other PT series variants for similar dimensions and electrical characteristics. Cross-reference with other Mallory Sonalert piezoelectric buzzers ensuring matching voltage, frequency, and mounting type compatibility.
