PSR-28N08A-JQ

Speakers Overview

The PSR-28N08A-JQ is an electromagnetic speaker manufactured by Mallory Sonalert Products Inc. It features a round shape with a 28 mm diameter and a depth of 4.3 mm. The unit utilizes a ferrite magnet and a Mylar cone, providing an impedance of 8 Ohms and a power rating of 250 mW. It operates at a frequency of 700 Hz with a sound pressure level of 89 dBA. Termination is achieved via solder pads.

Speakers Feature Summary

• Electromagnetic transducer design using a ferrite magnet and Mylar cone for audio output
• Round form factor with 28 mm diameter suitable for compact panel integration
• Direct solder pad termination style for straightforward circuit board mounting

Speakers Applications

• Industrial equipment status indication
• Control panel audio signaling
• General purpose electromechanical alerting systems

Speakers Procurement Notes

Verify the specific suffix JQ against official Mallory documentation to confirm exact material or termination variations. Ensure the 8 Ohm impedance and 250 mW power rating align with the driving circuit capabilities. Confirm RoHS compliance status through current manufacturer declarations as regulatory requirements may evolve.

Speakers Selection Notes

Select this component when a low-frequency 700 Hz tone is required for audible alerts. The 8 Ohm impedance dictates specific driver requirements compared to higher impedance alternatives. The Mylar cone material offers durability in standard industrial environments. Verify that the 28 mm diameter fits within the available enclosure space constraints.

Speakers Part Context

This part belongs to the Mallory Sonalert speakers and transducers category. It represents an electromagnetic solution distinct from piezoelectric buzzers found in other product lines. The series focuses on basic audio indication tasks rather than complex multi-tone generation.
