SC250FJ

Overview

The SC250FJ is a piezoelectric buzzer from the Mallory Sonalert SC series, designed for panel mounting with a diameter of 42.85mm and maximum height of 35.54mm. It operates on AC or DC voltages ranging from 60V to 250V, drawing between 4mA and 14mA. The device emits a continuous tone at a frequency of 2.9kHz with a sound pressure level of 52dB measured at 60V and 61cm distance. Termination is provided via screw terminals and quick-connect tabs measuring 0.250 inches (6.35mm).

Feature Summary

• Features an internal driver circuit allowing direct connection to power sources without external oscillators.
• Utilizes piezoelectric technology to generate audible alerts in industrial environments.
• Supports both screw terminal and quick-connect tab termination styles for flexible wiring integration.

Applications

• Industrial machinery status indication
• Equipment fault warning systems
• Control panel audio signaling

Procurement Notes

Verify the specific suffix designation against official Mallory Sonalert documentation to confirm exact electrical characteristics and termination style. Confirm voltage ratings and current consumption align with system requirements before procurement. Ensure environmental operating temperatures meet application needs.

Selection Notes

Select this component when a high-voltage AC/DC compatible indicator is required. The integrated driver simplifies circuit design by eliminating external drive components. Verify physical dimensions fit available panel cutouts and ensure adequate clearance for mounting hardware.
