ZT028LDCTB15

Overview

The ZT028LDCTB15 is an industrial-grade audio indicator manufactured by Mallory Sonalert Products Inc. It operates on a DC input and features internally driven circuitry for alarm functions. The device utilizes piezoelectric technology to generate sound at a frequency of 3.9 kHz with a continuous tone pattern. It delivers a sound pressure level of 95 dBA and is rated for 28 VDC operation with a current draw of 40 mA. The unit is designed for panel mounting using terminal block connections and carries an IP66 rating for environmental protection.

Feature Summary

• Industrial-grade construction with IP66 ingress protection rating
• Internally driven circuitry for simplified integration
• Continuous tone output at 3.9 kHz frequency
• Terminal block connection method for secure wiring

Applications

• Industrial control panels requiring audible status indication
• Machine tool safety warning systems
• Factory automation equipment alarms
• Process control system alerts

Procurement Notes

Verify the specific suffix configuration against the manufacturer datasheet to ensure correct voltage, tone, and LED color specifications. Confirm terminal block compatibility with existing wiring harnesses. Check for RoHS compliance requirements relevant to the target deployment region. Ensure panel cutout dimensions match the physical housing size before ordering.

Selection Notes

Select this model when a loud, continuous audible alert is required in harsh industrial environments. The IP66 rating makes it suitable for washdown areas or dusty conditions. Verify that the 28VDC supply matches the available power source. Consider the 40mA current consumption for power budget calculations. Compare with other ZT series variants if different tones or voltages are needed.
