SC250N

Overview

The SC250N is a piezoelectric buzzer from the SC series, designed for panel mounting with threaded terminals. It operates on AC or DC input within a voltage range of 60 to 250V and draws a supply current between 5 and 18mA. The device generates a sound pressure level of 68dB at 60V measured at 61cm. It functions at a frequency of 2.9kHz in a short pulse mode. The unit has a diameter of 42.85mm and a maximum installation height of 35.54mm. It supports an operating temperature range of -30°C to 65°C.

Feature Summary

• Internal driver circuitry allows direct connection without external components
• Piezoelectric technology ensures reliable acoustic output
• Threaded terminal connections provide secure panel mounting

Applications

• Industrial alarm systems
• Equipment status indication
• Control panel signaling

Procurement Notes

Verify the specific suffix against official Mallory Sonalert documentation to confirm exact electrical characteristics and termination style. Confirm compliance requirements such as RoHS status prior to ordering. Ensure the selected variant matches the required voltage and pulse specifications for the target application environment.

Selection Notes

Select this component when high-voltage AC or DC operation is required for audible alerts. The internal driver simplifies circuit design by eliminating the need for separate oscillator circuits. Verify that the 68dB sound pressure level meets the ambient noise requirements of the installation site.

Part Context

This part belongs to the SC series of industrial audio indicators manufactured by Mallory Sonalert Products Inc.
