SC616QR

Overview

The SC616QR is an internally driven piezoelectric buzzer from the Mallory Sonalert SC series, designed for audible indication and alert signaling. It operates on a DC input voltage range of 6 to 16V with a current consumption of 3 to 12mA. The device produces a chirp tone at a frequency of 2.9kHz, achieving a sound pressure level of 68dB at 6V measured at a distance of 61cm. It features panel mount installation with screw terminals and quick-connect tabs (0.250 inch). The unit has a diameter of 42.85mm and functions within a temperature range of -30°C to 65°C.

Feature Summary

• Internally driven piezoelectric technology for simplified circuit integration
• Chirp operating mode providing distinct auditory alerts
• Dual termination options including screw terminals and quick-connect tabs

Applications

• Electronic equipment audible indication
• Alert signaling in industrial control panels
• Safety warning systems requiring distinct chirp tones

Procurement Notes

Verify RoHS compliance status as documentation indicates REACH exemption but varying regulatory listings. Confirm terminal type requirements against available screw or tab configurations. Check manufacturing lead times as items are often made-to-order. Ensure voltage supply aligns with the 6-16VDC operational range to maintain specified acoustic performance.

Selection Notes

Select this model when a chirp tone is required rather than continuous or warble sounds. The internal driver eliminates external oscillator components. Verify panel cutout dimensions match the 42.85mm diameter. Consider the 68dB SPL rating for environmental noise levels. Compare current draw specifications against power budget constraints for low-power applications.

Part Context

Part of the Mallory Sonalert SC series of industrial buzzers. Shares common mounting dimensions and voltage ranges with other SC variants like SC616N and SC616WXY. Differentiated by its specific chirp waveform and internal drive capability. Designed for robust performance in demanding industrial environments.

Replacement Considerations

SC616N offers continuous tone; SC616WXY provides multiple tones. Verify acoustic output differences if tone change affects system functionality. Mounting compatibility remains consistent across the SC series.
