MSS5PH

Alarms, Buzzers, And Sirens Overview

The MSS5PH is an internally driven magnetic buzzer manufactured by Mallory Sonalert Products Inc. It operates on a rated voltage of 5 V DC with a supply range of 4 to 6 V. The device produces a sound pressure level of 85 dB at 5 V measured from 10 cm distance, with a frequency of 2.075 kHz. Current consumption ranges from 46 mA to 150 mA. It features through-hole PC pin termination and measures 23x23 mm. The unit is certified by UL and cUL for medical grade applications.

Alarms, Buzzers, And Sirens Feature Summary

• Internally driven electromagnetic design eliminates the need for external oscillator circuits
• Through-hole mounting with PC pins for standard PCB integration
• Medical grade certification suitable for healthcare equipment applications

Alarms, Buzzers, And Sirens Applications

• Medical diagnostic and monitoring equipment
• Industrial control panels requiring audible alerts
• Consumer electronics with internal drive requirements

Alarms, Buzzers, And Sirens Procurement Notes

Verify that the specific order matches the MSS5PH part number exactly, as similar models like MSS5MMP may have different current ratings or packaging. Confirm that the application environment stays within the -30°C to 55°C operating temperature range. Ensure the power supply provides stable DC voltage between 4 V and 6 V to maintain specified acoustic performance. Check for UL/cUL certification requirements if deploying in regulated medical or industrial sectors.

Alarms, Buzzers, And Sirens Selection Notes

Select this component when an internally driven solution is required to simplify circuit design. The 5 V rating aligns with standard logic levels. Consider the 85 dB output sufficient for moderate noise environments. The 23x23 mm form factor fits standard through-hole footprints. Verify that the 46-150 mA current draw is supported by the system power budget.

Alarms, Buzzers, And Sirens Part Context

This component belongs to the MSS series of magnetic buzzers from Mallory Sonalert. The series includes variants such as MSS5MMP and MSS5ELMFP. These devices are designed for audible indication in electronic systems. The MSS5PH specifically targets applications requiring built-in driving capabilities without external components.

Alarms, Buzzers, And Sirens Replacement Considerations

The MSS5MMP is a comparable internally driven magnetic buzzer in the same series. Verify electrical parameters and physical dimensions before substitution. Ensure replacement parts meet the same UL/cUL medical grade certifications if required by the original design specifications.
