SC616NPR

Overview

The SC616NPR is an industrial piezoelectric buzzer from the Mallory Sonalert SC series. It operates on a DC voltage range of 6 to 16VDC with a current draw of 3 to 12mA. The device produces a fast pulse tone at a frequency of 2.9kHz and achieves a sound pressure level of 68dB at 6V measured at 61cm. It features panel mount installation with screw terminals and quick-connect tabs measuring 0.250 inches (6.35mm). The unit has a diameter of 42.85mm and a maximum height of 35.54mm.

Feature Summary

• Internal driver circuitry for direct connection
• Piezoelectric transducer technology
• Fast pulse operational mode
• CUL approval certification

Applications

• Industrial machinery status indication
• Equipment alarm signaling
• Control panel audio alerts

Procurement Notes

Verify the specific suffix against official Mallory Sonalert documentation to confirm terminal type and acoustic output. Confirm RoHS compliance status as indicated in current datasheets. Check authorized distributor availability due to potential supply constraints. Ensure mounting hole dimensions match the 42.85mm diameter specification before procurement.

Selection Notes

Select this model for applications requiring a fast pulse alert within a 6-16VDC system. Compare the 68dB SPL rating against ambient noise levels to ensure audibility. Verify that the screw and quick-connect terminal options suit the available wiring infrastructure. Consider the 42.85mm diameter for panel cutout requirements.

Part Context

This component belongs to the SC series of industrial buzzers manufactured by Mallory Sonalert Products Inc. The series is designed for robust audio indication in demanding environments. The SC616NPR variant specifically offers fast pulse functionality with CUL approval, distinguishing it from continuous or warble tone variants within the same family.

Replacement Considerations

SC616QR is a documented substitute offering chirp tone characteristics with identical physical dimensions and electrical interfaces.
