TUHCH-88B-930-Q(M)

Overview

The TUHCH-88B-930-Q(M) is a panel-mount piezoelectric buzzer from the Twin Turbo series by Floyd Bell Inc. It features an internally driven indicator circuit and operates on DC input within a voltage range of 9 to 30 Vdc. The unit produces an extra loud medium chime tone at a frequency of 3000±250 Hz. With a diameter of 1.300 inches (33.02mm), it draws between 65 and 125 mA during operation.

Feature Summary

• Internally driven piezoelectric driver for simplified integration
• Produces an extra loud medium chime tone
• Panel mount design with 33.02mm diameter
• Operates on DC voltage inputs

Applications

• Industrial equipment status indication
• Control panel alarm signaling
• Safety warning systems requiring high volume output

Procurement Notes

Verify the specific operating mode matches the requirement for a medium chime tone, as other variants in the series offer different tones such as slow warble or continuous. Confirm the voltage supply aligns with the 9-30 Vdc specification to ensure proper function. Check that the panel cutout accommodates the 33.02mm diameter. Ensure the application environment is compatible with the plastic housing material.

Selection Notes

Select this model when a high-volume audible signal is required without external driving components. The internal driver simplifies circuit design compared to passive buzzers. Consider the Twin Turbo series if higher sound pressure levels are needed compared to standard piezo buzzers. Verify that the medium chime tone is appropriate for the intended alert type rather than a continuous or warbling tone.

Part Context

This component belongs to Floyd Bell's Twin Turbo series of piezoelectric buzzers. These devices are designed for applications demanding high acoustic output in compact form factors. The series typically includes various mounting options and tone configurations to suit different industrial and commercial signaling needs.

Replacement Considerations

Direct substitutes may include other models from the Twin Turbo series with similar dimensions and electrical characteristics. Verify compatibility regarding the specific chime tone and voltage range before substitution.
