AST1427M-05TRQ

Overview

The Mallory Sonalert AST1427M-05TRQ is an externally driven electromagnetic transducer designed for audio indication. It operates on a peak-to-peak AC input voltage ranging from 3V to 7V, with a rated voltage of 5V. The device produces a sound pressure level of 89dB at a frequency of 2731Hz. Its compact physical dimensions are 11mm x 14mm x 3mm, suitable for space-constrained panel mounting applications requiring precise signal-driven acoustic output.

Feature Summary

Externally driven electromagnetic transducer technology
Low voltage AC peak-to-peak signal compatibility
Compact rectangular form factor for tight spaces

Applications

Panel-mounted industrial control indicators
Electronic equipment status signaling
Consumer appliance audio alerts

Procurement Notes

Verify the specific ordering suffix and tape packaging configuration when sourcing. Confirm that the supplier provides official datasheets matching the AST1427M-05TRQ designation. Ensure the component meets RoHS compliance requirements for your region. Cross-reference the manufacturer's part number to avoid confusion with similar electromagnetic series variants.

Selection Notes

Select this model when external circuitry controls the tone generation rather than internal drivers. Choose based on the 3-7V AC VPP input requirement and 89dB output capability. Consider the 11x14x3mm footprint against available panel space. Validate that the electromagnetic type suits the environmental conditions compared to piezoelectric alternatives.

Part Context

This component belongs to the Mallory Sonalert electromagnetic transducer family. It differs from internally driven buzzers by requiring an external oscillator or microcontroller to generate the drive signal. The product line focuses on reliable, low-voltage audio indication solutions for various electronic assemblies.
