Overview
The SC250FPR is an industrial-grade 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 consumption of 14mA. The device produces a short pulse tone at a frequency of 2.9kHz and delivers a sound pressure level between 62dB and 70dB. Physical dimensions are 1.69 inches in length and width, with a height of 1.41 inches. Termination is achieved via screw terminals.
Feature Summary
- Industrial-grade construction suitable for demanding environments
- Internal driver circuitry allows direct connection to power sources
- Short pulse operation mode for distinct auditory signaling
Applications
- Industrial machinery fault indication
- Control panel status alerts
- Safety system warning signals
Procurement Notes
Verify the specific voltage rating required for your application against the 60-250VAC/DC range. Confirm that the screw terminal termination style matches your wiring infrastructure. Ensure the short pulse tone characteristic meets the auditory requirements of the installation environment. Check for RoHS compliance documentation if regulatory adherence is mandatory for the project.
Selection Notes
Select this component when high visibility audio alerts are needed in industrial settings. The wide voltage tolerance simplifies integration into various control systems. Consider the physical size constraints as it requires a standard panel cutout. Compare with other SC series models if continuous tone or different mounting styles are preferred over the short pulse configuration.
Part Context
This part belongs to the Mallory Sonalert SC series, which specializes in robust piezoelectric alarms. The manufacturer has a long history in electronic signaling devices. This series is known for reliability in harsh conditions. The SC250FPR variant specifically targets applications requiring moderate volume output with a pulsed signal pattern for clear differentiation from background noise.
Replacement Considerations
SC250FJR is a similar model within the same series offering comparable electrical characteristics and form factor. Verify terminal type and tone duration specifications before substitution.
