TUHCH-88R-930-Q(F)

Overview

The TUHCH-88R-930-Q(F) is a panel-mount piezoelectric buzzer from the Turbo series by Floyd Bell Inc. It features an internally driven indicator circuit and accepts DC input within a voltage range of 9 to 30 VDC. The unit operates at a frequency of 3000±250 Hz and produces an extra loud fast chime tone. Designed for rugged environments, it offers IP68 protection. The device utilizes quick connect tabs with 0.250-inch (6.35mm) terminals and has a diameter of 1.300 inches (33.02 mm).

Feature Summary

• Internally driven piezoelectric design for direct DC connection without external drivers.
• IP68 rated construction ensuring durability in rugged and harsh environmental conditions.
• Extra loud fast chime tone operation providing clear audible alerts.

Applications

• Industrial alarm systems requiring high visibility and audibility.
• Heavy machinery notification units operating in dusty or wet environments.
• Safety alert indicators for equipment monitoring.

Procurement Notes

Verify the exact suffix configuration against official datasheets to ensure correct terminal type and acoustic output specifications. Confirm that the required voltage range aligns with your system's power supply capabilities. Check for any specific mounting hole dimensions if custom panel integration is planned. Ensure compatibility with existing wiring harnesses using standard quick-connect tabs.

Selection Notes

Select this model when high sound pressure levels are critical for safety notifications in noisy industrial settings. The internal driver simplifies circuit design by eliminating the need for separate oscillator components. Consider the IP68 rating if the installation site is exposed to water jets or dust ingress. Verify that the 9-30V DC input matches the available control voltage.

Part Context

This component belongs to Floyd Bell Inc's Turbo series of alarms and buzzers. The series is characterized by robust construction and high-output acoustic performance. Similar models in the lineup may vary in voltage range, tone pattern, or terminal style, but share the same fundamental panel-mount form factor and piezoelectric technology.

Replacement Considerations

Direct substitutes include other Floyd Bell Turbo series models such as TLHB-88R-930-Q(F) or TUHW-88R-930-Q(F), provided they match the specific voltage and acoustic requirements. Cross-manufacturer replacements must be evaluated for dimensional fit, electrical characteristics, and environmental sealing ratings.
