MSS5D

Alarms, Buzzers, And Sirens Overview

The MSS5D is a magnetic buzzer manufactured by Mallory Sonalert Products Inc., designed for through-hole mounting. It operates on a rated voltage of 5 V DC with a supply current range of 46 to 150 mA. The device produces a sound pressure level of 85 dB at 5 V measured at 10 cm and functions at a frequency of 2.075 kHz. It features internal drive circuitry and utilizes PC pin termination. The unit is certified by UL and cUL, meets medical grade standards, and operates within a temperature range of -30°C to 55°C.

Alarms, Buzzers, And Sirens Procurement Notes

Verify the specific suffix or variant against the official datasheet to ensure correct acoustic output and electrical characteristics. Confirm that the through-hole package dimensions match the target PCB layout. Check for required certifications such as UL or cUL depending on the end-use region. Ensure the operating voltage aligns with the system power supply to prevent damage.

Alarms, Buzzers, And Sirens Selection Notes

Select this component when a low-profile, internally driven magnetic buzzer is required for medical or industrial applications. The 5 V rating suits standard logic-level power supplies. Consider the 85 dB SPL for environments requiring moderate audible alerts. Verify thermal constraints against the -30°C to 55°C operating range before deployment in extreme conditions.

Alarms, Buzzers, And Sirens Part Context

This part belongs to the MSS series of audio indicators from Mallory Sonalert. The series includes various magnetic and piezoelectric buzzers tailored for different mounting styles and acoustic needs. The MSS5D specifically addresses the need for reliable, low-cost audible signaling in compact electronic assemblies.

Alarms, Buzzers, And Sirens Replacement Considerations

Consult the manufacturer's cross-reference guide for verified substitutes. Generic replacements may differ in SPL, current draw, or mounting footprint. Ensure any alternative maintains the same voltage rating and internal drive capability to avoid circuit redesign.
