TUHB-88W-930-Q(U)

Overview

The TUHB-88W-930-Q(U) is a panel mount chime alarm from the AudioLarm II series by Floyd Bell Inc. It utilizes piezoelectric technology for sound generation and features an internally driven indicator circuit. The device operates on a DC voltage range of 5 to 25 volts, drawing between 5 and 25 mA. It produces a frequency of 2.9 kHz with a sound pressure level of 70 dB at 5V measured at 61 cm. The unit measures 1.410 inches in diameter and 1.480 inches in maximum height, with wire leads for termination. It is rated IP68 for dust tightness and waterproofing, suitable for operation between -20°C and 65°C.

Feature Summary

• Piezoelectric chime alarm with integrated internal driver circuit
• IP68 rated enclosure providing dust tight and waterproof protection
• Panel mount design with top-positioned port and wire lead termination

Applications

• Industrial machinery status indication
• Heavy equipment warning systems
• Harsh environment control panels requiring water resistance

Procurement Notes

Verify the specific suffix (U) against official documentation to confirm exact termination or mounting variations. Ensure the operating voltage aligns with the 5-25V DC specification. Confirm UL/UR approval requirements for the target installation region. Cross-reference the IP68 rating with environmental exposure needs.

Selection Notes

Select this component when high durability and water resistance are required for audible signaling. The wide voltage input range allows flexibility in power supply design. The compact panel-mount form factor suits limited space applications. Verify that the 70 dB SPL meets the ambient noise requirements of the intended deployment site.

Part Context

This model belongs to the AudioLarm II series, recognized as a widely used industrial alarm line. It replaces older analog indicators with solid-state piezo technology. The series emphasizes reliability in demanding environments, offering consistent performance across varying temperature ranges and electrical conditions.

Replacement Considerations

Consult official substitution lists for direct equivalents. Generic replacements may lack the specific IP68 sealing or internal driver compatibility. Verify mechanical dimensions and terminal types before adopting alternative sources.
