ZT028LAFP1G

Overview

The ZT028LAFP1G is an industrial piezoelectric buzzer from the ZT series by Mallory Sonalert. It operates on a 20 VDC supply with a current draw of 40 mA. The device emits a fast pulse tone at 3.9 kHz with a sound pressure level of 85 dBA measured at 61 cm. It features terminal block connections and panel mount installation. The unit includes an integrated LED indicator and meets IP66 ingress protection standards.

Feature Summary

• Integrates an internal driver for direct connection to control circuits
• Combines audible alarm with visual LED status indication
• Provides high environmental sealing for harsh industrial settings

Applications

• Industrial machinery fault signaling
• Control panel status monitoring
• Safety equipment alarm systems

Procurement Notes

Verify the specific suffix G against the manufacturer datasheet to confirm exact acoustic and electrical characteristics. Ensure the terminal block interface matches the system wiring requirements. Confirm that the 20 VDC rating aligns with the available power supply voltage in the target application environment.

Selection Notes

Select this model when both audio and visual alerts are required in a single component. The 20 VDC specification suits low-voltage DC control systems. The IP66 rating makes it suitable for washdown areas or dusty environments where standard indicators would fail.

Part Context

This component belongs to the ZT series, which combines buzzer and LED functions. It shares the 22 mm mounting footprint with other Mallory Sonalert industrial alarms. The design prioritizes dual-mode alerting for critical machine status notifications.

Replacement Considerations

Check ZA028LAFP1 for AC/DC compatibility differences. Verify ZT028LDFP1R if red LED color is mandatory. Confirm ZT028LAIC1G if continuous tone is preferred over pulse.
