ZT120LAFP1B

Overview

The ZT120LAFP1B is a piezoelectric buzzer indicator manufactured by Mallory Sonalert Products Inc. It operates on an AC/DC input voltage range of 48 to 120V and draws a supply current of 40mA. The device produces a sound pressure level of 85dB at 90V measured at a distance of 61cm, with a frequency of 3.9kHz. It features internal drive circuitry for direct connection applications. The unit utilizes terminal block connections and is designed for panel mount installation.

Feature Summary

• Piezoelectric technology for reliable acoustic output
• Internally driven circuitry simplifies integration
• Terminal block termination for secure wiring
• Panel mount design for industrial enclosure integration

Applications

• Industrial control panels
• Medical equipment alarms
• Transportation systems

Procurement Notes

Verify the specific ordering suffix against the manufacturer's official datasheet to ensure correct voltage and mounting specifications. Confirm that the terminal block type matches the system wiring requirements. Check for RoHS compliance status if environmental regulations apply to the project. Ensure the operating temperature range meets the intended environment conditions before finalizing procurement.

Selection Notes

Select this component when a high-intensity audible alarm is required for panel-mounted applications. The internal driver eliminates the need for external driving circuits, reducing board space and complexity. Verify that the 48-120V AC/DC input aligns with the available power supply in the target system. Consider the 85dB SPL rating for environments requiring clear auditory alerts.

Part Context

This part belongs to the ZT series of industrial-grade audio indicators from Mallory Sonalert. The series is known for robust construction and compliance with safety standards such as UL and cUL. These devices are commonly used in harsh environments where reliability and clear signaling are critical for operational safety and status indication.

Replacement Considerations

Consult the official Mallory Sonalert cross-reference guide for verified substitute part numbers. Ensure any replacement maintains the same voltage range, current draw, and mounting configuration. Verify that the acoustic performance and physical dimensions are compatible with the existing enclosure design.
