SC208NR

Overview

The SC208NR is an internally driven piezoelectric buzzer manufactured by Mallory Sonalert Products Inc. Designed for indicator and alert applications, it operates on a DC input voltage range of 1.8 to 8V. The device produces a loud continuous tone with a frequency of approximately 2.9kHz. It features panel mount installation and utilizes screw terminals for connection. The unit is RoHS compliant and suitable for environments requiring reliable acoustic signaling within the specified electrical parameters.

Feature Summary

• Internally driven piezoelectric technology for direct connection
• Produces a loud continuous tone for clear auditory alerts
• Supports low voltage operation from 1.8V to 8V DC
• Panel mount design with screw terminal connections

Applications

• Industrial equipment status indicators
• Low voltage control panel alarms
• Consumer appliance audio feedback
• Automotive interior warning systems

Procurement Notes

Verify the specific voltage rating and tone type against the official datasheet before procurement. Confirm that the 1.8-8VDC operating range aligns with the system power supply. Ensure the panel mount configuration and screw terminal interface are compatible with the enclosure design. Check for any regional compliance requirements such as RoHS or REACH if applicable to the final assembly.

Selection Notes

Select this component when a low-voltage, internally driven audible alarm is required. The wide input voltage range allows flexibility in power supply design. The continuous tone mode is distinct from pulsed variants, making it suitable for steady-state warnings. Consider the physical dimensions and mounting style to ensure proper integration into the target housing.

Part Context

This part belongs to the Mallory Sonalert product line, specializing in piezoelectric buzzers and sirens. The SC series typically denotes industrial-grade audio indicators. As an internally driven unit, it simplifies circuit design by eliminating the need for external oscillators or drivers, reducing component count and board space.
