SC616NJ

Overview

The SC616NJ is an industrial-grade piezoelectric audio indicator manufactured by Mallory Sonalert. It operates on a DC voltage range of 6 to 16 VDC with a rated voltage of 16 V. The device draws a current of 30 mA and produces a continuous tone at a frequency of 2900 Hz. It features a sound pressure level of 82 dBA measured at 6 VDC and 94 dBA at 16 VDC. The unit is designed for panel mounting with a diameter of 42.85 mm (1.687 in) and a height of 35.8 mm (1.41 in). It utilizes quick connect tabs for termination and is constructed with a black nylon housing.

Feature Summary

• Internally driven piezoelectric technology eliminates the need for external driver circuitry.
• Panel mount design with knurled nut attachment for secure installation.
• Wide operating temperature range suitable for industrial environments.

Applications

• Industrial machinery status indication
• Control panel alarm systems
• Equipment failure alerts

Procurement Notes

Verify the specific suffix against official Mallory Sonalert documentation to confirm electrical characteristics, as variations exist within the SC series. Confirm terminal type and mounting dimensions match the enclosure requirements. Check RoHS compliance status if required by project specifications. Ensure the driving circuit provides stable DC voltage within the 6-16 VDC range.

Selection Notes

Select this component when a high-decibel, internally driven audible alert is required for panel-mounted applications. The SC616NJ offers a balance of loudness and low current consumption. Compare with other SC series variants if different tones or voltage ratings are needed. Ensure the mounting hole size corresponds to the recommended 30 mm diameter for proper fitment.

Part Context

The SC616NJ belongs to the SC series of industrial audio indicators from Mallory Sonalert. This series is characterized by robust construction and reliable performance in demanding environments. The components are typically used where clear auditory feedback is critical for operational safety and monitoring.
