ZT028LAIC3R

Overview

The ZT028LAIC3R is an internally driven piezoelectric buzzer with integrated red LED, manufactured by Mallory Sonalert Products Inc. It operates on a voltage range of 20 to 28 VDC and draws a current of 50 mA. The device produces a sound pressure level of 85 dB at 20 V measured at 61 cm, with an operating frequency of 3.9 kHz. Designed for panel mounting via terminal block connections, it combines acoustic signaling with visual indication in a single industrial component.

Feature Summary

• Integrates piezoelectric buzzer and red LED indicator
• Internally driven circuitry simplifies interface requirements
• Panel mount configuration with terminal block termination

Applications

• Industrial control panels requiring combined audio-visual alerts
• Machine status indication systems
• Safety warning devices for heavy equipment

Procurement Notes

Verify the specific suffix against the manufacturer datasheet to confirm electrical characteristics and mechanical dimensions. Ensure the terminal block type matches the design board layout. Confirm RoHS compliance status if required by project specifications before finalizing procurement orders.

Selection Notes

Select this component when both audible alarm and visible light indication are necessary within a confined panel space. The internal drive capability reduces external component count compared to externally driven alternatives. Verify that the 20-28 VDC input range aligns with the system power supply architecture.

Part Context

This part belongs to the ZT series of industrial buzzers from Mallory Sonalert. The series focuses on high-intensity audio and visual signaling solutions for demanding environments. The ZT028LAIC3R specifically addresses applications needing simultaneous dual-modality feedback without complex external driver circuits.

Replacement Considerations

Consult official cross-reference lists for direct substitutes. Verify pinout compatibility and mounting hole patterns before swapping with other models. Ensure replacement parts maintain equivalent SPL ratings and voltage tolerances.
