ZT028LAMP1R

Overview

The ZT028LAMP1R is an industrial piezoelectric buzzer from the ZT series by Mallory Sonalert Products Inc. It operates on a 28 VDC supply with a current draw of 40 mA. The device emits a pulse tone at a frequency of 3.9 kHz and achieves a sound pressure level of 85 dBA at 61 cm. It features terminal block connections for panel mounting and carries cUL and UL certifications.

Feature Summary

• Integrates internal drive circuitry for direct connection to control signals without external drivers.
• Provides high-intensity audible alerts suitable for noisy industrial environments.
• Constructed with robust materials to withstand harsh operational conditions.

Applications

• Industrial machinery status indication
• Factory automation alarm systems
• Control panel audio signaling

Procurement Notes

Verify the specific suffix R against official Mallory documentation to confirm terminal configuration and acoustic output specifications. Ensure the operating voltage matches the 28 VDC requirement. Confirm that the terminal block interface aligns with existing wiring harnesses. Check for RoHS compliance if required by project standards.

Selection Notes

Select this model when a compact, internally driven buzzer is required for 28 VDC systems. The 30.74 mm diameter fits standard 22 mm panel cutouts. Consider the 85 dBA output level relative to ambient noise. Verify that the pulse tone pattern meets safety signaling requirements.

Part Context

This component belongs to the ZT series of 22 mm panel-mount alarms. It complements other ZT variants like ZT028LAIC1G and ZT028LDIC2R, which offer different tones or integrated LED options. The series provides standardized dimensions for easy retrofitting in industrial enclosures.

Replacement Considerations

Direct substitutes include ZT028LAMP1 for continuous tone applications. For integrated LED functionality, consider ZT028LDIC2R. Verify pinout compatibility before swapping models within the ZT family.
