AST612TRQ

Overview

The AST612TRQ is a surface-mount magnetic audio transducer manufactured by Mallory Sonalert Products Inc. It operates within an input voltage range of 8 to 16 V peak-to-peak and oscillates at a frequency of 2.4 kHz, with a tolerance of ±400 Hz. The device delivers a sound pressure level of 87 dB and supports a wide operating temperature range from -30°C to 85°C. Designed for SMD assembly, this component lacks internal circuitry, requiring external drive signals.

Feature Summary

• Surface-mount package design for automated PCB assembly
• Magnetic transducer technology without internal driving circuitry
• Washable construction suitable for harsh industrial environments

Applications

• Industrial control panel indicators
• Commercial appliance status alerts
• Automotive electronic system warnings

Procurement Notes

Verify the specific suffix TRQ against official Mallory documentation to confirm tape-and-reel packaging requirements. Ensure the AC input signal matches the 8–16 Vp-p specification. Confirm RoHS compliance status via current manufacturer certificates before finalizing procurement orders.

Selection Notes

Select this component when surface-mount integration is required for magnetic buzzer applications. The absence of internal drivers necessitates compatible external oscillator circuits. Verify that the 87 dB output meets acoustic requirements for the target enclosure size and ambient noise levels.

Part Context

This part belongs to the Mallory Sonalert magnetic transducer family. Unlike piezoelectric buzzers, it requires external drive electronics. The series offers robust performance in high-temperature environments, distinguishing it from standard commercial audio components.

Replacement Considerations

No public substitute part numbers are documented for this specific model.
