SC616N-BTR

Overview

The SC616N-BTR is a piezoelectric industrial buzzer from the Mallory Sonalert SC series. It operates at a rated voltage of 16 VDC with a current draw of 22 mA. The device produces a continuous tone at a frequency of 2.9 kHz, achieving a sound pressure level of 103 dBA. It features solder lug terminals for connection and is designed for panel mounting. The physical dimensions are 43 mm in diameter and 1.41 inches in height.

Feature Summary

• Piezoelectric transducer technology for reliable audio indication
• High-output acoustic performance suitable for noisy environments
• Robust construction designed for industrial applications

Applications

• Industrial machinery status indicators
• Factory automation control panels
• Safety alarm systems

Procurement Notes

Verify the specific terminal configuration matches the design requirements, as this variant utilizes flat blade or solder lug connections distinct from screw-terminal models. Confirm that the operating environment temperature falls within the specified range to ensure long-term reliability. Cross-reference the datasheet for precise mounting hole dimensions and torque specifications during integration planning.

Selection Notes

Select this model when high acoustic output is required without integrated electronics. Compare against the SC616NPU if screw terminals are preferred over solder lugs. Consider the LSC616N if an integrated LED visual indicator is necessary alongside the audible alert. Ensure the driving circuit can supply the specified 22 mA current at 16 VDC continuously.

Part Context

This component belongs to the Classic Sonalert line, known for durable metal housing and consistent performance. The SC series represents standard industrial buzzers, while the suffix BTR typically denotes bulk packaging. It serves as a fundamental audio signaling element in larger electromechanical assemblies where simple, robust alerts are prioritized over complex programmable tones.

Replacement Considerations

Direct substitutes include other SC series variants like SC616NPU for different terminal styles. Verify compatibility with existing panel cutouts and wiring harnesses before substitution.
