PB-1220P-SGQ

Alarms, Buzzers, And Sirens Overview

The PB-1220P-SGQ is an externally driven magnetic transducer manufactured by Mallory Sonalert Products Inc. It operates at a rated voltage of 1.5 V with a peak-to-peak range of 1.25 to 2.5 V. The device consumes a maximum current of 32 mA and produces an oscillation frequency of 2.048 kHz. Acoustic performance is rated at 85 dB measured at 1.5 V and 10 cm distance. It utilizes through-hole PC pin termination for mounting.

Alarms, Buzzers, And Sirens Feature Summary

• Externally driven magnetic transducer design
• Low voltage operation capability
• Through-hole PC pin termination

Alarms, Buzzers, And Sirens Applications

• Battery-powered audio indicators
• Portable electronic devices
• Low-voltage alarm systems

Alarms, Buzzers, And Sirens Procurement Notes

Verify the specific acoustic output requirements against the 85 dB rating at 1.5 V and 10 cm. Confirm that the driving circuit can supply the necessary 32 mA current. Ensure the PCB layout accommodates the through-hole PC pin form factor. Check for RoHS compliance status in the official datasheet before finalizing procurement.

Alarms, Buzzers, And Sirens Selection Notes

Select this component when low voltage operation around 1.5 V is required. The external drive requirement means it lacks internal oscillator circuits. Consider the 2.048 kHz frequency for specific audible tone applications. Evaluate the 85 dB SPL for proximity alert scenarios rather than long-range alarms.

Alarms, Buzzers, And Sirens Part Context

This part belongs to the Mallory Sonalert piezo and magnetic transducer lineup. It serves as a sound-producing element requiring external signal generation. The product line focuses on industrial and consumer audio indication solutions.

Alarms, Buzzers, And Sirens Replacement Considerations

Cross-reference with other externally driven magnetic transducers from Mallory Sonalert. Verify matching voltage, current, and frequency specifications. Ensure physical dimensions and terminal types are compatible with existing designs.
