Overview
The ZT120LACTG is an industrial audible signal device manufactured by Mallory Sonalert Products Inc. It operates on a 120 VAC supply with a current rating of 40 mA. The unit produces a continuous tone at a frequency of 3.7 kHz with a sound pressure level of 95 dBA. Designed for panel mounting, it features terminal block termination and includes a green LED indicator. The component measures 22 mm in diameter and 43.5 mm in height.
Feature Summary
- Integrates an audible alarm with a visual green LED indicator for dual-status signaling
- Engineered for direct connection to 120 VAC power sources without external drivers
- Constructed with terminal block connections for secure panel installation
Applications
- Industrial machinery status indication
- Factory floor safety alarms
- Control panel warning systems
Procurement Notes
Verify the specific suffix 'G' against the manufacturer's latest datasheet to confirm the presence of the green LED and exact acoustic specifications. Ensure the input voltage matches the 120 VAC requirement before integration. Confirm that the terminal block wiring method aligns with the enclosure design constraints.
Selection Notes
Select this model when both audible and visual alerts are required simultaneously in a single housing. It is suitable for applications needing high visibility indicators alongside loud alarms. Consider the 22 mm mounting hole size during panel layout planning. Verify environmental ratings if exposure to moisture or dust is expected.
Part Context
This component belongs to the ZT series of industrial buzzers from Mallory Sonalert. The series is characterized by robust construction for harsh environments and integrated LED options. It serves as a standard solution for combining audio and visual warnings in compact industrial enclosures.
Replacement Considerations
Check for ZA120LACT variants if a different LED color is needed. Verify physical dimensions against existing cutouts. Ensure electrical compatibility with the 120 VAC circuit before substitution.
