AR027150MR-R

Overview

The AR027150MR-R is a round electromagnetic receiver manufactured by PUI Audio. It features a nominal impedance of 150 Ohms and a power rating of 15 mW. The device operates within a frequency range of 20 Hz to 10 kHz and delivers a sound pressure level of 118 dB. Designed for board mounting, it utilizes solder pad termination and incorporates a Mylar cone with a Neodymium Iron Boron magnet.

Feature Summary

• High acoustic output capability with 118 dB sensitivity
• Broad operational frequency response from 20 Hz to 10 kHz
• Compact round form factor suitable for space-constrained designs

Applications

• Medical equipment audio signaling
• Industrial control panel indicators
• Security and fire alarm systems
• Consumer electronics feedback

Procurement Notes

Verify the specific datasheet version for the AR027150MR-R to confirm mechanical dimensions and electrical tolerances prior to integration. Ensure that the driving circuitry can supply sufficient voltage to achieve the rated 118 dB output across the 150 Ohm impedance without exceeding the 15 mW power limit. Confirm RoHS compliance status through official manufacturer documentation before finalizing procurement.

Selection Notes

Select this component when high-volume acoustic output is required in a compact package. The 150 Ohm impedance suits applications where current limiting is preferred over high-current drive. Compare against lower impedance alternatives if the system design prioritizes voltage-driven efficiency rather than power handling capacity.

Part Context

This receiver belongs to PUI Audio's standard line of electromagnetic transducers. It shares design characteristics with other models in the AR series, such as the AR027300MR-R, differing primarily in impedance and acoustic tuning. These components are engineered for reliability in commercial and industrial audio signaling environments.

Replacement Considerations

The AR027150MR-2-R is a documented variant within the same product family. Verify compatibility regarding mechanical mounting and electrical parameters before substitution.
