Overview
The ZT028MDSP1R is an industrial-grade piezoelectric buzzer and indicator manufactured by Mallory Sonalert Products Inc. It operates on a voltage range of 20 to 28 VDC with a current draw of 40 mA. The device emits a fast pulse tone at a frequency of 3.9 kHz, achieving a sound pressure level of 95 dBA. It features integrated red LED illumination and terminal block connections for panel mounting.
Feature Summary
- Combines audible alarm with visual red LED indication
- Industrial grade construction with IP66 ingress protection
- Internal driver circuitry for direct connection
- Terminal block termination for secure wiring
Applications
- Industrial machinery status monitoring
- Control panel alarm systems
- Factory automation safety indicators
- Heavy equipment operational alerts
Procurement Notes
Verify the specific suffix configuration against official Mallory Sonalert documentation to ensure correct voltage, tone, and LED color specifications. Confirm that the terminal block interface matches the target panel wiring requirements. Check for RoHS compliance status if environmental regulations apply to the deployment environment.
Selection Notes
Select this model when both high-decibel audio warning and visible light indication are required in a single component. The 20-28 VDC operating range suits standard industrial control circuits. Ensure the panel cutout dimensions accommodate the 22 mm diameter housing and verify that the terminal block spacing aligns with the existing wiring infrastructure.
Part Context
This unit belongs to the ZT series of industrial audio indicators designed for harsh environments. The series emphasizes durability and clear signaling through combined acoustic and optical outputs. It utilizes piezoelectric technology for reliable operation across specified temperature ranges without external drivers.
Replacement Considerations
Direct substitutes within the same series include ZA028LAFP1 for AC/DC compatibility or ZT028LAIC1G for continuous tone variants. Verify that replacement models maintain the required IP66 rating and terminal block mounting style to ensure physical and electrical interchangeability.
