Overview
The SC250HPR is a piezoelectric buzzer from the Mallory Sonalert SC series, designed for industrial audio indication. It operates on AC or DC voltages ranging from 60V to 250V with a typical current draw of 16mA. The device emits a fast pulse tone at a frequency of 4500Hz. It features a sound pressure level of approximately 75dBA and utilizes screw terminals for connection. The unit is constructed for panel mounting with dimensions of 42.85mm in diameter and 35.54mm in height.
Feature Summary
- Piezoelectric technology providing reliable acoustic output without internal drivers
- Fast pulse operational mode for distinct auditory signaling
- Screw terminal interface ensuring secure electrical connections
- Panel mount design compatible with standard industrial enclosures
Applications
- Industrial machinery status indicators
- Process control alarm systems
- Electrical panel monitoring alerts
- Transportation vehicle warning signals
Procurement Notes
Verify that the application voltage falls within the 60V to 250V AC/DC range to ensure proper operation. Confirm that the required acoustic signature matches the fast pulse characteristic at 4500Hz. Ensure the mounting hole diameter accommodates the 42.85mm form factor. Check terminal compatibility with existing wiring harnesses before finalizing procurement specifications.
Selection Notes
Select this model when a high-frequency fast pulse alert is required for critical system notifications. Choose based on the need for robust piezoelectric performance in varying environmental conditions. Consider the screw terminal option if vibration resistance is a priority over quick-connect styles. Evaluate the 75dBA output against ambient noise levels to guarantee audibility in the intended installation environment.
Part Context
This component belongs to the SC series of industrial alarms manufactured by Mallory Sonalert Products Inc. The series is recognized for its durability and consistent performance in demanding environments. The SC250HPR variant specifically addresses applications requiring rapid, high-pitched auditory warnings through its fast pulse configuration.
Replacement Considerations
SC250HR offers a continuous tone alternative within the same series. SC250KR provides a short pulse option with different acoustic characteristics. SC250JR delivers a slow pulse variant for distinct signaling patterns. Verify dimensional and electrical compatibility when substituting with these related models.
