Overview
The ZT120LACTR30 is an industrial piezoelectric buzzer manufactured by Mallory Sonalert Products Inc. It operates on a voltage rating of 120 VAC with a current draw of 40 mA. The device produces a continuous tone at a frequency of 3.9 kHz, achieving a sound pressure level of 95 dBA. It features terminal block termination and panel mount installation. The unit has a diameter of 30.74 mm and a height of 43.5 mm. It includes yellow LED illumination and supports a 30-second flash mode operation.
Feature Summary
- Integrates visual and audible signaling through combined piezoelectric sound generation and yellow LED illumination.
- Supports dual operational modes including continuous tone output and timed flash functionality for distinct alert patterns.
- Designed for industrial environments with robust construction suitable for panel mounting applications.
Applications
- Industrial machinery status indication
- Control panel alarm signaling
- Equipment fault notification systems
Procurement Notes
Verify the specific suffix R30 against official Mallory Sonalert documentation to confirm the reel packaging configuration and exact electrical tolerances. Ensure the 120 VAC input matches the target circuit design before integration. Cross-reference the terminal block specifications with existing wiring harnesses to guarantee physical compatibility during installation.
Selection Notes
Select this component when both high-decibel audible alerts and visible light indicators are required in a single enclosure space. The 120 VAC rating makes it suitable for direct connection to standard industrial control voltages without additional transformers. Consider the 30.74 mm diameter for panel cutout requirements and verify that the 95 dBA output meets the ambient noise environment criteria.
Part Context
This part belongs to the ZT series of industrial audio indicators from Mallory Sonalert. The series is characterized by its ability to combine multiple signaling modalities into a compact form factor. The ZT120LACTR30 specifically targets applications requiring reliable performance under standard industrial AC power conditions.
Replacement Considerations
The ZA120LACT is a similar industrial buzzer offering comparable voltage ratings and sound levels but lacks the integrated LED feature. Verify if the absence of visual indication is acceptable for the replacement application.
