SC616JR

Overview

The SC616JR is an industrial piezoelectric buzzer from the Mallory Sonalert SC series, designed for panel mounting. It operates on a DC input voltage range of 6 to 16 VDC with a rated voltage of 16 V. The device draws a supply current between 3 and 12 mA. It features a chirp tone at a frequency of 2.9 kHz, producing a sound pressure level of 68 dBA at 6 VDC measured at 2 feet. The unit has a diameter of 42.85 mm (1.687 inches) and a maximum height of 35.54 mm (1.399 inches). Termination is provided via quick connect tabs measuring 0.250 inches (6.35 mm).

Feature Summary

• Internally driven piezoelectric transducer generating a chirp tone.
• Panel mount design with knurled nut attachment for secure installation.
• Compatible with standard 30 mm (1.181 inch) mounting holes.

Applications

• Industrial control panels requiring audible alerts.
• Factory automation equipment status indication.
• Heavy machinery operator interfaces.

Procurement Notes

Verify the specific suffix against official Mallory Sonalert documentation to confirm the exact acoustic mode and termination style. Ensure the ordering part number matches the required voltage rating and sound pressure level specifications for the target application environment.

Selection Notes

Select this component when an internally driven, high-force piezoelectric indicator is required for panel mounting. Confirm that the operating temperature range of -30°C to +65°C meets the environmental conditions. Verify that the 30 mm hole size fits the enclosure design constraints.

Part Context

This component belongs to the SC series of industrial audio indicators manufactured by Mallory Sonalert Products Inc. The series is characterized by robust construction suitable for harsh environments, offering various acoustic modes including continuous, pulse, and chirp tones for different alerting needs.

Replacement Considerations

Consult official Mallory Sonalert cross-reference guides for verified substitutes. Ensure any replacement maintains the same voltage range, current draw, and physical mounting dimensions to fit existing panel cutouts without modification.
