ZT028LASP1R

Overview

The ZT028LASP1R is an industrial piezoelectric buzzer from the ZT series by Mallory Sonalert. It operates on a 20-28 VDC supply with a current rating of 40 mA. The device produces a continuous tone at 3.9 kHz with a sound pressure level of 85 dBA. It features terminal block connections and panel mount installation. The unit measures 30.74 mm in diameter and 43.44 mm in height, offering IP66 ingress protection.

Feature Summary

Internally driven piezoelectric alarm providing audible alerts without external circuitry
Continuous tone output for steady state warning applications
Terminal block termination for secure electrical connection
Panel mount design suitable for industrial enclosure integration

Applications

Industrial machinery status indication
Control panel alarm signaling
Equipment fault detection systems
Safety interlock auditory warnings

Procurement Notes

Verify the specific voltage range and tone type against project requirements before ordering. Confirm that the terminal block interface matches existing wiring infrastructure. Ensure the panel cutout dimensions align with the specified diameter to guarantee proper fit. Check for any regional compliance certifications required for the intended deployment environment.

Selection Notes

Select this model when a continuous audible signal is required for industrial environments. The internal drive capability simplifies circuit design compared to externally driven buzzers. Consider the IP66 rating for applications requiring dust and water resistance. Verify that the 20-28 VDC operating range matches the available control power supply.

Part Context

This component belongs to the ZT series of industrial audio indicators. The series is characterized by robust construction and high sound pressure levels. It serves as a direct replacement for older models requiring similar form factors and electrical specifications. The manufacturer provides application notes for mounting and wiring guidelines.
