CES-3990-158PM-67

Overview

The CES-3990-158PM-67 is a round, top-port speaker manufactured by Same Sky. It utilizes Neodymium Iron Boron magnets and features an 8 Ohm impedance with a 1.5W power rating. The device delivers a sound pressure level of 100 dBA at a resonant frequency of 1350 Hz. Designed for industrial environments, it offers IP67 ingress protection. The unit employs wire lead termination and is suitable for panel mounting applications requiring durable audio output.

Feature Summary

• IP67 rated enclosure for dust and water resistance
• Neodymium Iron Boron magnetic structure
• Top port acoustic design

Applications

• Industrial control panels
• Outdoor electronic equipment
• Medical devices requiring sealed audio alerts

Procurement Notes

Verify the specific suffix PM-67 to confirm the IP67 sealing and wire lead configuration. Ensure the 8 Ohm impedance matches the amplifier output requirements. Confirm the 1350 Hz frequency response aligns with the intended audible alert application. Check RoHS compliance documentation for regulatory adherence in target markets.

Selection Notes

Select this component when high environmental sealing is required alongside moderate power handling. The 1.5W rating suits low-to-medium volume signaling. Consider the 100 dBA sensitivity for distance requirements. The wire lead format simplifies integration into custom assemblies without additional connectors.
