SC616JU

Overview

The SC616JU is a piezoelectric buzzer from the Mallory Sonalert SC series, designed for industrial audio indication. It operates on a DC voltage range of 6 to 16V and draws a current of approximately 40 mA. The device features a panel mount configuration with screw terminals for secure installation. It produces a warble tone at a frequency of 2.8 kHz with a sound pressure level of 77-85 dBA. The unit has a diameter of 43 mm and a height of 1.41 inches.

Feature Summary

• Piezoelectric transducer technology for reliable audio signaling
• Internal drive circuitry for direct connection to power sources
• Warble tone output mode for distinct auditory alerts
• Panel mount design with screw terminal connections

Applications

• Industrial machinery status indicators
• Control panel alarm systems
• Equipment fault detection units
• Safety warning devices in manufacturing environments

Procurement Notes

Verify the specific tone variant and terminal type against project requirements before ordering. Confirm availability through authorized distributors as stock levels fluctuate. Ensure the mounting hole dimensions match the enclosure design. Check for any recent product change notifications that may affect specifications or compliance status.

Selection Notes

Select this model when a warble tone is required for high-visibility alerts. The 6-16VDC operating range suits standard low-voltage industrial control circuits. Consider the 43mm diameter for panel space constraints. Verify that the 77-85 dBA output meets local noise regulations for the intended installation location.

Part Context

This component belongs to the SC series of industrial buzzers manufactured by Mallory Sonalert Products Inc. The series is characterized by robust construction suitable for harsh environments. Similar models in the lineup include variants with different tones such as continuous chirp or multiple tones, offering flexibility for various signaling needs.

Replacement Considerations

Direct substitutes within the same series include SC616N-2 for constant tone applications and SC616QR for chirp modes. Ensure replacement parts maintain the same voltage range and mounting dimensions to fit existing enclosures without modification.
