SC250HP

Overview

The SC250HP 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 current draw of 16mA. The device produces a fast pulse tone at a frequency of 4.5kHz and delivers a sound pressure level of 80dBA. It features internal drive circuitry and utilizes screw terminals or quick connect tabs (0.250 inch) for connection. The unit measures 1.69 inches in diameter and 1.41 inches in height, suitable for panel mounting.

Feature Summary

Piezoelectric construction for reliable high-voltage operation
Internal driver circuitry simplifies integration
Fast pulse output mode for distinct alerting
Dual termination options including screw terminals

Applications

Industrial machinery status indicators
High-voltage control panel alarms
Factory automation safety warnings
Heavy equipment operational alerts

Procurement Notes

Verify the specific suffix HP against official Mallory Sonalert documentation to confirm the fast pulse characteristic and 4.5kHz frequency. Ensure the input power supply matches the 60-250V AC/DC range. Confirm terminal type requirements align with available screw or quick-connect options. Check RoHS compliance status if required by project specifications.

Selection Notes

Select this component when a high-decibel, fast-pulse alarm is required for industrial environments. The wide voltage tolerance allows direct connection to various control circuits without external drivers. Consider the physical dimensions for panel cutout compatibility. Compare with other SC series variants if continuous tone or different frequencies are needed.

Part Context

This part belongs to the Mallory Sonalert SC series of industrial buzzers. These devices are engineered for durability in harsh conditions. The series offers various tones and mounting styles. The SC250HP specifically addresses applications requiring immediate attention through its rapid pulsing sound profile.

Replacement Considerations

SC250HR provides a continuous tone variant within the same series. SC250DP offers a different pulse rate. Verify electrical parameters and mechanical fit before substitution.
