SW400704-1

Overview

The SW400704-1 is a rectangular waterproof speaker from the DB Unlimited Agile 67 Series, designed for robust audio output in demanding environments. It features a 4-ohm impedance and operates at a rated frequency of 750 Hz with a power handling capacity of 2 watts. The unit utilizes a Polyethylene Terephthalate (PET) cone and incorporates top porting for acoustic efficiency. Its physical dimensions are 40 mm x 28.4 mm x 11.8 mm, providing a compact form factor suitable for space-constrained applications requiring IP67 protection.

Feature Summary

• IP67 waterproof rating for reliable operation in wet or harsh conditions
• Rectangular frame design with top porting configuration
• Polyethylene Terephthalate (PET) cone material for durability

Applications

• Medical devices requiring sterilization resistance
• Industrial equipment exposed to moisture
• Security and surveillance systems
• Transportation and automotive electronics

Procurement Notes

Verify the specific datasheet version for the SW400704-1 to confirm current RoHS compliance status and exact dimensional tolerances. Ensure that the mounting interface aligns with the PCB or chassis design, as this is a through-hole or surface-mount component depending on the specific variant configuration. Cross-reference the pinout diagram during integration to prevent polarity errors.

Selection Notes

Select this model when high reliability in wet environments is critical, given its IP67 certification. The 4-ohm impedance and 2W rating suit low-voltage battery-operated systems. Consider the rectangular footprint and 11.8 mm height for enclosure clearance. Compare against standard round speakers if directional sound or specific mounting constraints dictate a non-circular geometry.

Part Context

This component belongs to the Agile 67 Series by DB Unlimited, which specializes in sealed, waterproof micro-speakers. The series targets applications needing durable audio solutions where standard speakers would fail due to environmental exposure. DB Unlimited focuses on providing advanced audio components for medical, industrial, and security sectors, emphasizing engineering support and custom design capabilities alongside standard parts.

Replacement Considerations

No direct public substitute part numbers are confirmed for the SW400704-1. Replacement requires matching the 4-ohm impedance, 2W power rating, IP67 rating, and 40x28.4mm rectangular dimensions. Verify acoustic performance and mounting hole patterns before substituting with other waterproof speaker models.
