Overview
The PT-2038PQ is a piezoelectric buzzer from the Mallory Sonalert product line, designed for audible alerting applications. It operates within a supply voltage range of 5V to 25V DC and draws a maximum operating current of 5mA. The device produces a constant tone at a frequency of 2.9 kHz with a sound pressure level of approximately 95 dBA. It utilizes through-hole termination for PCB mounting and is RoHS compliant.
Feature Summary
- Piezoelectric transducer technology for reliable audio indication
- Low power consumption suitable for battery-operated systems
- Through-hole PCB mounting for secure integration
Applications
- Industrial control panel alarms
- Medical device status indicators
- Consumer electronics warning signals
Procurement Notes
Verify the specific voltage rating and current consumption against your system requirements before procurement. Confirm that the through-hole footprint matches your PCB design. Ensure compliance with RoHS directives if required by your manufacturing standards. Check for any specific environmental ratings if the application involves extreme temperatures or humidity.
Selection Notes
Select this component when a low-current, constant-tone indicator is needed for PCB-mounted applications. It is suitable for designs requiring operation across a wide voltage range from 5V to 25V. Consider its compact form factor and high acoustic output for visibility in noisy environments. Compare with other Sonalert series if terminal block or screw mount options are preferred instead of PCB mounting.
Part Context
The PT-2038PQ belongs to the Mallory Sonalert family of audible indicators. This brand is recognized for providing standard panel alarms and medical alerts. The SC628 series shares similar operational principles but differs in mounting style and voltage ranges. Mallory Sonalert products are widely used in industrial, medical, and transportation sectors for critical signaling needs.
