ZT028LDMT2R

Overview

The ZT028LDMT2R is an industrial-grade buzzer and sound indicator manufactured by Mallory Sonalert. It operates on a 24 VDC supply with a current rating of 40 mA. The device produces a slow chime tone at a frequency of 3.9 kHz, achieving a sound pressure level of 95 dBA. It features a red LED and utilizes terminal block connections for panel mounting. The unit has an IP66 rating and measures 22 mm in diameter with a height of 43.44 mm.

Feature Summary

• Combines audible alarm with visual LED indication
• IP66 rated enclosure for environmental protection
• Terminal block connection style
• Panel mount installation format

Applications

• Industrial machinery status monitoring
• Factory automation control panels
• Equipment fault signaling systems
• Process alarm interfaces

Procurement Notes

Verify the specific voltage requirement against the system design, as this model is rated for 24 VDC. Confirm that the terminal block interface matches the existing wiring infrastructure. Ensure the mounting hole dimensions accommodate the 22 mm diameter specification. Check regional availability restrictions noted by distributors.

Selection Notes

Select this component when a high-decibel audible alert combined with a visual indicator is required for industrial environments. The IP66 rating makes it suitable for harsh conditions where dust and water resistance are necessary. Consider the terminal block termination method if screw-down wiring is preferred over PCB mounting.
