CDS-3646-16-SP

Overview

The CDS-3646-16-SP is a piezoelectric siren manufactured by Same Sky. It operates at a nominal voltage of 12 VDC and produces a sound pressure level of 105 dB. The device features a continuous tone output and includes an integrated driving circuit for direct interface with control logic. Constructed with a plastic housing, it provides environmental protection rated at IP67. The unit utilizes wire leads for electrical connection and measures 46 mm in diameter.

Feature Summary

Integrated driving circuit enables direct connection to standard logic levels without external drivers
Piezoelectric transducer generates high-intensity continuous acoustic signals
IP67 sealed enclosure ensures resistance to dust ingress and temporary water immersion

Applications

Industrial machinery status indicators
Safety alarm systems in manufacturing environments
Public address sirens requiring high volume output

Procurement Notes

Verify the specific acoustic frequency and mounting configuration against application requirements before ordering. Confirm that the wire lead termination style matches existing harness designs. Ensure the operating environment temperature range aligns with the component's specified limits. Check for any regional compliance certifications required for industrial deployment.

Selection Notes

Select this model when a high-decibel continuous warning signal is necessary. The integrated driver simplifies PCB or wiring design compared to passive buzzers. Consider the IP67 rating for applications exposed to harsh conditions. Compare dimensions against available panel space to ensure proper fitment during installation.

Part Context

This component belongs to the CDS series of piezoelectric sirens from Same Sky. The series offers various voltage options and sound pressure levels. The CDS-3646-16-SP represents a mid-range output option within the product line, balancing power consumption with acoustic intensity for general industrial signaling tasks.
