SM870508-1

Overview

The SM870508-1 is a round dynamic speaker manufactured by DB Unlimited, designed for flush-mount installation. It features an 8-ohm impedance and a nominal power rating of 10 watts. The unit delivers a sound pressure level of 103 dBA with a resonant frequency of 500 Hz. Its physical dimensions are 87 mm x 87 mm x 31 mm, utilizing a Mylar cone. The component operates within a temperature range of -20°C to +60°C and includes solder eyelets for termination.

Feature Summary

• IP54 rated enclosure providing protection against dust ingress and water jets
• Robust Mylar cone construction for reliable acoustic performance
• Flush-mount frame design facilitating secure integration into enclosures

Applications

• Industrial control panels requiring durable audio feedback
• Medical equipment housings needing sealed transducers
• Automotive instrumentation systems exposed to environmental stressors

Procurement Notes

Verify the specific datasheet version before procurement, as manufacturer specifications may undergo revisions. Confirm that the IP54 rating aligns with your environmental exposure requirements. Ensure the 10W power handling matches your amplifier output capabilities to prevent damage. Check for any RoHS compliance documentation if required by your manufacturing standards.

Selection Notes

Select this model when a high-output, environmentally sealed speaker is necessary for flush-mount applications. The 8-ohm impedance suits standard audio driver circuits. Consider the 87mm diameter for available panel space. The IP54 rating makes it suitable for harsher environments compared to standard open-frame speakers. Verify thermal limits for continuous operation in enclosed spaces.
