Overview
The ZT120LACTB15 is an industrial-grade piezoelectric buzzer with an integrated yellow LED indicator, manufactured by Mallory Sonalert Products Inc. It operates on a 120 VAC input and draws 40 mA of current. The device produces a continuous tone at a frequency of 3.9 kHz with a sound pressure level of 95 dBA measured at 61 cm. It features terminal block connections for secure wiring and is designed for panel mounting. The unit has a diameter of 22 mm and a height of 43.5 mm, utilizing a threaded front interface compatible with standard 22.5 mm panel holes.
Feature Summary
- Combines audible alarm and visual indication in a single compact industrial housing
- Features internally driven circuitry requiring no external driver components
- Includes a yellow LED indicator synchronized with the audio output
- Utilizes a threaded front mount design for secure panel installation
Applications
- Industrial machinery status monitoring
- Factory automation control panels
- Electrical distribution equipment signaling
- Heavy-duty safety warning systems
Procurement Notes
Verify that the application voltage matches the 120 VAC rating to ensure proper operation. Confirm that the panel cutout dimension aligns with the recommended 22.5 mm hole size for the threaded front mount. Check for RoHS compliance requirements if environmental regulations apply to the deployment site. Ensure the terminal block connection type suits the existing wiring infrastructure.
Selection Notes
Select this model when both audible and visual alerts are required simultaneously in industrial environments. The 95 dBA output ensures audibility in noisy settings. The internal drive simplifies circuit design by eliminating the need for separate oscillator components. Consider the physical dimensions and mounting style during enclosure design to ensure proper fit and accessibility for maintenance.
Part Context
This component belongs to the ZT series of industrial buzzers from Mallory Sonalert. The series is characterized by robust construction suitable for harsh environments. The ZT120LACTB15 specifically integrates a yellow LED with a continuous tone buzzer. It is part of a broader family of audio indicators offering various voltages and sound patterns.
Replacement Considerations
Direct substitutes within the same series include ZT120LACTY30 and ZT120LACTB. Verify that alternative models match the 120 VAC input and 95 dBA acoustic output. Ensure the replacement maintains the terminal block termination and panel mount configuration.
