CH-09-301-S(F)

Overview

The CH-09-301-S(F) is an internally driven piezoelectric buzzer manufactured by Floyd Bell Inc. It operates at a nominal voltage of 220 V with a current draw of 40 mA. The device produces an acoustic output of 93 dB at the rated voltage and frequency. The operating frequency is specified at 2.9 kHz. The unit features a panel mount design with screw terminal connections for secure installation.

Feature Summary

• Internally driven piezoelectric indicator circuit
• High sound pressure level output capability
• Panel mount construction with screw terminal termination

Applications

• Industrial control panel alarms
• High-voltage equipment status indicators
• Commercial building safety systems

Procurement Notes

Verify the specific voltage rating requirements against the application circuit, as this component is designed for 220 V operation. Confirm that the mounting hole dimensions align with the 1.409-inch diameter specification. Ensure the enclosure supports the seated height of 1.380 inches. Check for RoHS compliance documentation if required by project specifications.

Selection Notes

Select this model only when a high-voltage AC input is available directly, as it is not suitable for low-voltage DC systems without additional drivers. Compare the 93 dB output against ambient noise levels to ensure audibility. Consider the physical size constraints due to the large diameter and height relative to standard low-profile buzzers.

Part Context

This part belongs to the Floyd Bell Inc alarm and buzzer product line. It is categorized under internally driven piezoelectric devices. The manufacturer provides various models with different voltage ratings and acoustic outputs for diverse industrial signaling needs.

Replacement Considerations

Direct substitutes must match the 220 V rating and 2.9 kHz frequency. Verify mechanical compatibility with the 1.409-inch diameter and screw terminal interface. Models like CH-09-201-S(F) may differ in voltage or tone characteristics.
