Overview
The ZT028LDSR9R is an industrial-grade audio indicator manufactured by Mallory Sonalert. It features a 22 mm diameter piezoelectric buzzer with an integrated red LED for combined visual and audible signaling. The unit operates on a DC voltage range of 20 to 28 VDC. It utilizes a terminal block connection method for secure panel mounting. The device is designed for robust alarm applications requiring reliable notification in industrial environments.
Feature Summary
- Integrates a piezoelectric sounder with a red LED for simultaneous audio and visual alerts
- Designed for industrial environments with durable construction
- Utilizes terminal block connections for secure electrical interfacing
Applications
- Industrial machinery status indication
- Alarm systems requiring combined visual and audible warnings
- Control panel monitoring indicators
Procurement Notes
Verify the specific suffix configuration against official Mallory Sonalert documentation to ensure correct voltage, tone, and LED color specifications. Confirm terminal block compatibility with existing wiring harnesses. Check current availability status as supply may be restricted or limited in certain regions. Ensure the selected variant meets required environmental protection standards for the intended installation location.
Selection Notes
Select this model when a 22 mm form factor is required for panel cutouts. Choose based on the 20-28VDC operating range to match control system power supplies. Consider the terminal block interface if screw-down wiring is preferred over PCB mounting. Verify that the integrated red LED provides sufficient visibility for the specific application lighting conditions.
Part Context
This component belongs to the ZT series of industrial audio indicators from Mallory Sonalert. The series is characterized by compact 22 mm designs suitable for dense panel layouts. These units typically combine piezoelectric sounders with LEDs to provide multi-sensory feedback. The ZT series is engineered for reliability in demanding industrial settings.
Replacement Considerations
Direct substitutes within the same series include variants with different tones or LED colors, such as ZT028LDIC2R or ZT028LAIC1G. Ensure any replacement maintains the 20-28VDC input range and 22 mm mounting dimensions. Verify that the terminal block pinout remains compatible with existing wiring configurations.
