Overview
The SC250FKR is a piezoelectric buzzer from the Mallory Sonalert SC series, designed for panel mounting. It operates on AC or DC voltages ranging from 60V to 250V with a current draw of 14mA. The device emits a short pulse tone at a frequency of 2900 Hz and produces a sound pressure level of 62-70 dB. It features screw terminals for connection and has a diameter of 42.85mm.
Feature Summary
- Piezoelectric technology for reliable audio indication
- Internal driver circuitry simplifies integration
- Compatible with wide AC/DC voltage ranges
- Panel mount design with screw terminal connections
Applications
- Industrial machinery status indicators
- Control panel alarm systems
- Equipment fault detection alerts
- Safety warning signals in manufacturing environments
Procurement Notes
Verify the specific suffix 'KR' against official Mallory Sonalert documentation to confirm terminal type and pulse characteristics. Ensure the operating voltage range aligns with system requirements. Check RoHS compliance status if required by project specifications. Confirm availability through authorized distributors as lead times may vary.
Selection Notes
Select this component when a high-voltage piezo buzzer with short pulse output is required. Compare with SC250DP for fast pulse or SC250HR for continuous tone options. Consider the 42.85mm diameter for panel cutout dimensions. Verify terminal compatibility with existing wiring infrastructure before finalizing the selection.
Part Context
Part of the SC series industrial alarms, the SC250FKR provides audible alerts for critical systems. It complements other variants like SC250FK and SC250FJR within the same product family, offering distinct pulse patterns and acoustic outputs for diverse industrial signaling needs.
Replacement Considerations
SC250FK and SC250FJR are related models in the SC series. Verify functional equivalence regarding voltage, current, and acoustic output before substitution. Consult manufacturer datasheets for detailed pinout and dimensional comparisons.
