PT-2736WQ

Overview

The PT-2736WQ is a passive piezoelectric transducer manufactured by Mallory Sonalert Products Inc. It operates with a rated voltage of 5.0 Vp-p and a maximum operating voltage of 30 Vp-p. The device draws a maximum current consumption of 5 mA. Its resonant frequency is specified at 3.5 kHz, with a tolerance of ±500 Hz. The acoustic output is rated at 90 dB. Designed for panel mounting via wire leads, it functions as an externally driven alarm component.

Feature Summary

• Externally driven passive piezoelectric design
• Capable of transferring high amplitude or long duration pulses without saturation

Applications

• Industrial alarm systems
• Electronic equipment audio indicators
• Panel-mounted warning devices

Procurement Notes

Verify the specific datasheet version to confirm exact tolerances and environmental ratings. Ensure the driving circuit can supply the required peak-to-peak voltage within the 30 Vp-p limit. Confirm that the passive nature requires an external oscillator source for operation.

Selection Notes

Select this component when a high-amplitude pulse capability is required without internal drive electronics. The 5V rated voltage suits low-voltage logic interfaces. Verify that the 3.5kHz frequency aligns with the target application's auditory requirements and hearing protection standards.

Part Context

This part belongs to the Mallory Sonalert piezoelectric transducer family. It is distinct from active buzzers as it lacks an integrated oscillator. The design focuses on robustness for industrial environments, utilizing a flange mount style for secure panel installation.

Replacement Considerations

No direct public substitute part numbers are confirmed in the provided documentation. Any replacement must match the 3.5kHz resonant frequency, 5V rated voltage, and 90dB output level.
