ZA028SDCT

Alarms, Buzzers, And Sirens Overview

The ZA028SDCT is a piezoelectric buzzer from the Mallory Sonalert ZA series, designed for panel mounting. It operates on DC input within a voltage range of 16 to 28V and draws 40mA. The device produces a sound pressure level between 65 and 75dB at 3.3kHz. It features terminal block connections and includes internal drive circuitry. The unit measures 30.74mm in diameter with a maximum installation height of 56.75mm.

Alarms, Buzzers, And Sirens Feature Summary

• Integrates internal drive circuitry for direct connection to power sources without external drivers.
• Constructed with piezoelectric technology to generate audible alerts efficiently.
• Designed for secure panel mounting using standard M22 x 1.5 threads.

Alarms, Buzzers, And Sirens Applications

• Industrial control panels requiring visual and audible status indicators
• Equipment alarm systems needing reliable acoustic signaling
• Safety interlock circuits for machinery monitoring

Alarms, Buzzers, And Sirens Procurement Notes

Verify the specific suffix code against official Mallory Sonalert documentation to confirm exact electrical parameters such as frequency tolerance and sound pressure level variations. Ensure the procurement specification matches the required DC voltage range and terminal block orientation for proper integration into the target assembly.

Alarms, Buzzers, And Sirens Selection Notes

Select this component when a self-contained, internally driven piezoelectric buzzer is required for industrial environments. Consider the 30.74mm form factor and M22 mounting thread compatibility with existing panel cutouts. Evaluate the 65-75dB output range against ambient noise levels to ensure adequate audibility for the intended application scenario.

Alarms, Buzzers, And Sirens Part Context
