ZT120LAMP1R

Overview

The ZT120LAMP1R is an industrial audio indicator manufactured by Mallory Sonalert Products Inc. It operates on a 90-120 VAC supply with a current draw of 40 mA. The device produces a continuous tone at a frequency of 3.9 kHz, achieving a sound pressure level of 85 dBA at 61 cm. It features terminal block connections and panel mount installation. The unit includes an opaque white front cap made of 6/6 nylon and utilizes a M22 x 1.5 thread for mounting.

Feature Summary

• Internally driven piezoelectric buzzer providing audible alerts
• Integrated LED indicator with opaque white front cap
• Designed for direct AC line voltage operation without external drivers
• Panel mount construction with standard M22 threading

Applications

• Industrial machinery status indication
• Control panel alarm signaling
• Factory automation equipment monitoring
• Electrical cabinet safety warnings

Procurement Notes

Verify the specific suffix configuration against the manufacturer's current sales outline drawing to ensure compatibility with required voltage and acoustic specifications. Confirm that the M22 x 1.5 mounting thread matches the enclosure cutout dimensions. Check for RoHS compliance documentation if environmental regulations apply to the deployment site. Ensure the terminal block wiring method aligns with existing control panel standards.

Selection Notes

Select this model when a combined visual and audible alert is required for high-voltage AC environments. The internal drive circuitry simplifies design by eliminating external driver components. Verify that the 85 dBA output level meets occupational noise exposure requirements for the intended installation location. Consider the physical depth and diameter constraints within the panel assembly before finalizing the component choice.

Part Context

This component belongs to the ZT series of industrial audio indicators from Mallory Sonalert. The series is characterized by robust construction suitable for harsh industrial environments. These units typically integrate both sound and light functions into a single panel-mount package. The ZT series supports various voltage ratings and acoustic profiles to accommodate diverse signaling needs across different industrial sectors.

Replacement Considerations

Cross-reference part numbers such as ZT120LACTY30 or ZA028LAMP1 only if voltage and acoustic parameters match exactly. Verify that any substitute maintains the same M22 x 1.5 mounting interface and terminal block connection type. Ensure the replacement unit offers equivalent sound pressure levels and operating frequencies to maintain system consistency.
