Overview
The ZT028MDIC1Y is a panel-mount industrial buzzer manufactured by Mallory Sonalert Products Inc. It operates on a 24V DC supply and features a 30.74mm diameter housing with terminal block connections. The device produces a continuous tone at a frequency of 3.9 kHz with a sound pressure level of 95 dBA. It draws a current of 25 mA and is designed for robust industrial environments, offering reliable audio indication through its piezoelectric mechanism.
Feature Summary
- Industrial-grade construction suitable for demanding operational environments
- Integrated piezoelectric transducer for consistent acoustic output
- Terminal block interface for secure electrical connection
Applications
- Industrial machinery status indication
- Control panel alarm systems
- Equipment fault signaling
Procurement Notes
Verify the specific tone type and voltage rating against project requirements before ordering. Confirm that the terminal block connection method aligns with existing wiring infrastructure. Ensure the 24V DC supply matches the system power distribution. Check for any specific environmental certifications required for the installation site.
Selection Notes
Select this model when a high-decibel continuous alert is required for 24V DC industrial applications. Consider the 30.74mm mounting diameter for panel cutout compatibility. Evaluate the 95 dBA output against ambient noise levels to ensure audibility. Compare terminal block termination against screw or PCB mount options based on assembly needs.
Part Context
This component belongs to the ZT series of industrial buzzers from Mallory Sonalert. The series is characterized by durable housings and standardized mounting dimensions. These devices are engineered for long-term reliability in factory automation and heavy machinery sectors where clear auditory feedback is critical for safety and operation monitoring.
Replacement Considerations
Cross-reference with other ZT series models for similar voltage and mounting specifications. Verify that substitute parts maintain the same terminal block configuration and acoustic performance characteristics.
