ZT028LDFP1R

Overview

The ZT028LDFP1R is an industrial alarm and LED indicator manufactured by Mallory Sonalert. It operates at a rated voltage of 28 VDC with a current draw of 40 mA. The device produces a loud sound pressure level of 95 dBA at a frequency of 3.9 kHz using a fast pulse tone. It features a red LED and utilizes terminal block connections for panel mounting. The unit meets IP66 ingress protection standards and has physical dimensions of 30.7 mm x 43.44 mm.

Feature Summary

• Combines audible alarm and visual LED indication in a single industrial-grade unit
• Provides high-intensity acoustic output suitable for noisy environments
• Features robust environmental sealing for harsh industrial conditions
• Utilizes direct terminal block wiring for secure panel installation

Applications

• Industrial machinery status monitoring
• Factory safety warning systems
• Process control panel alarms
• Heavy equipment operator alerts

Procurement Notes

Verify the specific ordering suffix to confirm the exact voltage, sound pattern, and LED color configuration required for your application. Ensure the terminal block interface matches your existing wiring harness or panel cutout specifications. Confirm compliance requirements such as RoHS status prior to final procurement decisions.

Selection Notes

Select this model when a combined audio-visual alert is necessary for critical industrial notifications. The 28 VDC rating requires compatible power supplies. Consider the IP66 rating for washdown or dusty areas. Verify that the 95 dBA output level is appropriate for the ambient noise environment without causing hearing damage.

Part Context

This component belongs to the ZT series of industrial alarms from Mallory Sonalert. The series is designed for demanding environments requiring reliable auditory and visual signaling. The ZT series typically offers various voltage options and sound patterns to suit different industrial automation and safety applications.

Replacement Considerations

Check datasheets for alternative part numbers within the ZT series that match the 28 VDC requirement and terminal block mounting style. Ensure any substitute maintains the same IP66 rating and acoustic output levels for equivalent performance.
