ZT028LAFP1Y

Overview

The ZT028LAFP1Y is an industrial audio indicator from the Mallory Sonalert ZT series. It operates on a voltage range of 20-28 VAC and features a yellow LED. The device produces a fast pulse tone at a frequency of 3900 ± 500 Hz with a sound pressure level of 85-95 dBA. It utilizes terminal block connections for panel mounting and complies with RoHS standards.

Feature Summary

• Integrates a visual yellow LED indicator with an audible alarm function
• Designed for industrial environments with robust construction
• Utilizes terminal block termination for secure electrical connection

Applications

• Industrial machinery status indication
• Control panel alarm systems
• Equipment fault signaling

Procurement Notes

Verify the specific suffix Y against official Mallory Sonalert documentation to confirm the yellow LED variant. Ensure the input power supply matches the 20-28 VAC rating. Confirm terminal block compatibility with existing wiring harnesses before integration into the assembly design.

Selection Notes

Select this model when both audible alerts and visual confirmation are required in a single unit. The 22mm form factor fits standard industrial panel cutouts. Verify that the fast pulse acoustic profile meets the specific attention requirements of the target application environment.

Part Context

This component belongs to the ZT series of industrial alarms manufactured by Mallory Sonalert Products Inc.
