SCL028MD3MP1B

Alarms, Buzzers, And Sirens Overview

The SCL028MD3MP1B is a piezoelectric buzzer from the SCE series by Mallory Sonalert Products Inc. It operates on an AC/DC input voltage range of 16 to 28V with a current draw of 30mA. The device produces a medium pulse tone at a frequency of 2.9kHz, achieving a sound pressure level of 75dB at 16V measured at 61cm. Designed for panel mounting, it features screw terminals for connection and includes internal drive circuitry.

Alarms, Buzzers, And Sirens Feature Summary

• Integrates internal drive circuitry for direct operation without external oscillators
• Supports both AC and DC power supply inputs within the rated voltage range
• Features a medium pulse operational mode for distinct audio signaling

Alarms, Buzzers, And Sirens Applications

• Industrial control panels requiring audible status alerts
• Automotive instrumentation systems needing reliable voltage-tolerant indicators
• Medical equipment safety alarm circuits

Alarms, Buzzers, And Sirens Procurement Notes

Verify the specific acoustic output requirements against the 75dB rating at 16V before procurement. Confirm that the 30mA current consumption aligns with the system's power budget. Ensure the panel mounting hole dimensions accommodate the 42.85mm diameter housing. Check terminal compatibility with existing wiring harnesses for screw connections.

Alarms, Buzzers, And Sirens Selection Notes

Select this component when a medium pulse tone is required for clear differentiation in noisy environments. The wide voltage tolerance makes it suitable for applications with fluctuating power supplies. Compare against higher decibel models if greater audibility distance is necessary. Consider the physical size constraints relative to the 42.85mm diameter specification.

Alarms, Buzzers, And Sirens Part Context

This part belongs to the SCE series of industrial audio indicators. The series is characterized by robust construction and versatile electrical ratings. It serves as a standard solution for general-purpose alerting needs in harsh environments. The model number encodes specific voltage, frequency, and mechanical attributes defined by the manufacturer.

Alarms, Buzzers, And Sirens Replacement Considerations

Consult official cross-reference lists for verified substitutes. Ensure any replacement matches the 2.9kHz frequency and 75dB SPL to maintain signal consistency. Verify that alternative parts support the same 16-28V operating range and panel mounting configuration.
