ZA120SASR9

Overview

The ZA120SASR9 is an industrial-grade piezoelectric buzzer from the Mallory Sonalert ZA series, designed for panel mounting. It operates on a voltage range of 48 to 120 VAC/DC with a current rating of 40 mA. The device features a soft siren sweep tone operating between 3.15 and 4 kHz at a rate of 3 sweeps per second. It utilizes a terminal block connection type and includes a gasket for sealing. The unit is certified by cUL and UL, ensuring compliance with safety standards for industrial applications.

Feature Summary

• Generates a soft siren sweep tone within the 3.15 to 4 kHz frequency range
• Operates on wide voltage input ranging from 48 to 120 VAC or DC
• Includes internal driver circuitry for direct connection without external components
• Features a threaded M22 x 1.5 mount with integrated gasket for panel installation

Applications

• Industrial machinery status indication
• Factory floor alarm systems
• Control panel audio alerts
• Safety warning indicators in manufacturing environments

Procurement Notes

Verify the specific suffix configuration against official Mallory Sonalert documentation to ensure correct tone and voltage specifications. Confirm that the M22 threaded hole dimensions match the target panel cutout requirements. Check for updated certification marks such as cUL and UL compliance before finalizing procurement orders for regulated industrial equipment.

Selection Notes

Select this model when a soft siren sweep tone is required for less intrusive alerting compared to continuous buzzers. Ensure the application environment supports the 48-120 VAC/DC input range. Verify that the panel thickness accommodates the M22 thread depth and that the IP rating meets environmental exposure needs. Compare with other ZA series variants if different sound pressure levels or tones are necessary.

Part Context

This component belongs to the Mallory Sonalert ZA series of industrial audio indicators. These devices are characterized by their robust construction, panel-mount design, and compatibility with standard industrial control voltages. The ZA series is widely used in heavy machinery and automated systems where reliable visual and audible feedback is critical for operational safety and monitoring.

Replacement Considerations

Direct substitutes within the ZA series include models with similar voltage ratings and terminal block connections. Variants like ZA120LASR9 offer different tones but share the same form factor. Always verify electrical parameters and mounting dimensions before swapping parts to maintain system integrity and safety certifications.
