TUHO-88G-930-Q

Overview

The TUHO-88G-930-Q is an internally driven buzzer indicator manufactured by Floyd Bell Inc. It features a panel mount design with a diameter of approximately 33mm and a maximum height of 29.97mm. The device operates on a DC input voltage range of 9 to 30V, drawing between 65 and 125mA. It produces a frequency of 3kHz at a sound pressure level of 103dB when tested at 30V. The unit is rated for an operating temperature range of -20°C to 65°C and offers IP68 protection against dust and water.

Feature Summary

• Internally driven circuitry for direct connection
• Extra loud staccato tone output
• IP68 rated environmental sealing

Applications

• Industrial control panels requiring audible alerts
• Equipment status indication in harsh environments
• Security system alarm interfaces

Procurement Notes

Verify the exact part number spelling, as sources show variations like TLHO or TUHB. Confirm RoHS compliance status directly with the supplier. Ensure the required voltage range (9-30V) matches your system design. Check for specific mounting hole dimensions if panel integration is critical.

Selection Notes

Select this component for applications needing high-volume sound output in enclosed spaces. The internal driver simplifies PCB layout by removing external oscillator requirements. Consider the 33mm form factor for standard panel cutouts. Verify thermal tolerance against the expected ambient environment.

Part Context

This model belongs to the Floyd Bell TUH series of buzzers. It is designed for general-purpose audible signaling. The series typically includes variants with different frequencies and voltages. This specific unit emphasizes high decibel output for visibility in noisy settings.

Replacement Considerations

Check for TUHB-88G-930-Q(M) as a potential variant. Verify mechanical dimensions match existing panel cutouts. Ensure electrical specifications align with current supply rails before substitution.
