MB-09-301-W(F)

Alarms, Buzzers, And Sirens Overview

The MB-09-301-W(F) is an internally driven piezoelectric buzzer from the Floyd Bell Inc. AudioLarm II series, designed for panel mount installation. It operates on a DC input voltage range of 5 to 25V and draws a current between 5 and 25mA. The device generates a sound pressure level of 70dB at 5V measured at a distance of 61cm. Its operating frequency is fixed at 2.9kHz. The unit features wire leads for connection and has a diameter of 1.410 inches (35.81mm) with a maximum seated height of 1.480 inches (37.59mm). It is rated for operation in temperatures ranging from -20°C to 65°C.

Alarms, Buzzers, And Sirens Procurement Notes

Verify that the specific suffix (F) corresponds to the required lead configuration and acoustic output specifications. Confirm that the 5-25V DC operating range aligns with the target system power supply. Ensure the IP68 rating meets environmental exposure requirements. Check UL and UR approval agency listings if regulatory compliance is mandatory for the end application.

Alarms, Buzzers, And Sirens Selection Notes

Select this component when a self-contained, high-integrity audible indicator is required for harsh environments. The internal driver simplifies circuit design by eliminating external oscillators. Consider the 2.9kHz frequency and 70dB SPL for audibility needs. Verify physical dimensions fit the enclosure cutout. Compare against other AudioLarm II variants if different voltage ranges or mounting styles are needed.

Alarms, Buzzers, And Sirens Part Context

This part belongs to the Floyd Bell AudioLarm II series, which focuses on robust piezoelectric buzzers for industrial applications. The series offers various voltage ratings and mounting options. The MB-09-301-W(F) specifically targets low-voltage DC applications requiring reliable performance in wet or dusty conditions due to its sealed construction.

Alarms, Buzzers, And Sirens Replacement Considerations

Cross-reference with MB-09-301-W(M) or MB-09-301-W(S) for similar form factors but verify voltage and driver differences. Ensure substitute parts maintain the IP68 rating and panel mount compatibility.
