CH-V09-301-W(M)

Overview

The CH-V09-301-W(M) is a piezoelectric buzzer manufactured by Floyd Bell Inc, designed for panel mounting applications. It operates on a 220V AC input voltage and draws a supply current of 40mA. The device delivers a sound pressure level (SPL) of 93dB measured at 220V and a distance of 61cm. The unit features a top port location and is rated for an operating temperature range of -20°C to 65°C. The physical diameter is 35.81mm.

Feature Summary

• Piezoelectric transduction mechanism for audible signaling
• Panel mount construction with integrated volume control
• High-voltage direct AC operation capability

Applications

• Industrial equipment status indication
• Appliance alarm systems requiring high voltage drive
• Control panel auditory feedback units

Procurement Notes

Verify the specific suffix designation against official Floyd Bell documentation to confirm exact acoustic output characteristics and mounting hardware inclusion. Ensure the application environment remains within the specified -20°C to 65°C operating temperature range. Confirm that the 220V AC supply matches the component rating to prevent damage. Check for RoHS compliance requirements if applicable to your assembly standards.

Selection Notes

Select this component when a direct 220V AC drive source is available without additional driver circuitry. Consider the 93dB SPL output for environments requiring moderate to high audibility. Evaluate the 35.81mm diameter for panel cutout compatibility. Compare against lower voltage variants if system architecture requires DC or low-voltage AC inputs.

Part Context

This part belongs to the Floyd Bell V09 series of piezoelectric buzzers. The series typically includes variants with different tone types, such as beep or continuous alarms, and varying volume controls. The CH prefix often denotes specific acoustic or housing configurations within the manufacturer's lineup. Related models may include MB or MW prefixes indicating different tone profiles or connector styles.

Replacement Considerations

Direct substitutes are not explicitly confirmed in public datasheets. Similar functional replacements may include other 220V AC piezo buzzers from manufacturers like Honeywell or Murata, but electrical and mechanical parameters must be verified individually. Cross-referencing with Floyd Bell model MB-V09-301-Q(F) or MW-V09-530-W(F) may provide alternative tone or mounting options.
