SC616NR

Overview

The SC616NR is a piezoelectric audio indicator from the Mallory Sonalert SC series, designed for industrial applications. It operates on a voltage range of 6 to 16 VDC with a maximum current draw of 22 mA. The device produces a continuous tone at a resonant frequency of 2.9 kHz and achieves a sound pressure level of 95 dBA measured at a distance of 609.6 mm. It features screw terminals for connection and utilizes panel mount installation. The unit has a circular diameter of 43 mm and weighs approximately 45 g.

Feature Summary

• Piezoelectric transducer technology for reliable acoustic signaling
• High-intensity output capability suitable for noisy environments
• Robust construction designed for industrial-grade durability

Applications

• Industrial machinery status indication
• Factory floor safety alarms
• Equipment fault detection systems

Procurement Notes

Verify the specific terminal configuration and mounting requirements against the official datasheet before ordering. Confirm that the operating voltage range aligns with the system power supply. Check for any regional distribution restrictions or compliance certifications required for the target market. Ensure the panel cutout dimensions match the physical specifications provided in the documentation.

Selection Notes

Select this model when a high-decibel continuous tone is required for critical alerts. The wide voltage tolerance allows flexibility in power supply design. Consider the screw terminal style if direct wiring to terminal blocks is preferred over PCB mounting. Evaluate the physical size constraints to ensure compatibility with the enclosure design.

Part Context
