MSE28MDP2

Alarms, Buzzers, And Sirens Overview

The MSE28MDP2 is a piezoelectric buzzer from the Mallory Sonalert MSE series, designed for panel or board mounting. It features an internal driver circuit and operates on DC input within a voltage range of 16 to 28V. The device draws 50mA of current and produces a fast double pulse tone at a frequency of approximately 3.9kHz. It delivers a sound pressure level of 75-85dB. The unit utilizes solder pin termination for connection and measures 23mm x 23mm in footprint with a height of 14mm.

Alarms, Buzzers, And Sirens Feature Summary

• Internally driven piezoelectric technology eliminates the need for external oscillators
• Fast double pulse acoustic output pattern for distinct audible alerts
• Robust construction suitable for industrial environments

Alarms, Buzzers, And Sirens Applications

• Industrial machinery status signaling
• Control panel alarm indicators
• Equipment fault detection systems

Alarms, Buzzers, And Sirens Procurement Notes

Verify the specific acoustic profile and electrical ratings against the official Mallory Sonalert datasheet before integration. Confirm that the 16-28V DC operating range aligns with the target system power supply. Ensure mechanical dimensions and solder pin spacing match the PCB or panel layout requirements to prevent installation errors.

Alarms, Buzzers, And Sirens Selection Notes

Select this component when a self-contained audio indicator is required for high-voltage DC applications. The internal driver simplifies circuit design by removing the need for external drive transistors or logic gates. Consider the fast double pulse characteristic for urgent alert scenarios where standard continuous tones may be overlooked.
