Overview
The ZT028LDCM1R is an industrial piezoelectric buzzer from the Mallory Sonalert ZT series. It operates on a DC input voltage range of 20 to 28V with a rated voltage of 24V and a current consumption of 40mA. The device produces a continuous tone at a frequency of 3.9kHz with a sound pressure level of 85dB measured at 20V and 61cm. It features panel mount installation via terminal block connections, has a diameter of 22mm, and includes an integrated LED indicator.
Feature Summary
- Integrated visual and audio alerting capability combining a piezoelectric buzzer with an LED indicator
- Designed for industrial environments with robust construction suitable for control panels
- Provides continuous audible signaling without requiring external driver circuitry
Applications
- Industrial control panels requiring combined visual and auditory status indication
- Machine safety systems needing immediate operator alerts
- Process monitoring equipment in manufacturing settings
Procurement Notes
Verify the specific suffix code against official Mallory Sonalert documentation to confirm the exact acoustic output and LED color configuration. Ensure the terminal block connection type matches the wiring harness design. Confirm that the operating voltage range aligns with the system power supply specifications before procurement.
Selection Notes
Select this component when both audible alarms and visual indicators are required in a single unit. The ZT series offers high durability for harsh industrial conditions. Consider the terminal block mounting style if PCB mounting is not feasible. Verify that the 22mm form factor fits within the available panel space constraints.
Part Context
This part belongs to the ZT series of industrial alarms and buzzers manufactured by Mallory Sonalert Products Inc. The series is characterized by its rugged design, terminal block connectivity, and integration of LED indicators for enhanced visibility. These components are engineered for long-term reliability in demanding operational environments.
Replacement Considerations
Check for direct substitutes within the ZT series such as ZT028LDIC1R or ZA028LDMT6, ensuring compatibility with voltage, mounting, and acoustic requirements.
