UB-09-628-S(F)

Overview

The UB-09-628-S(F) is a piezoelectric chime alarm manufactured by Floyd Bell Inc, belonging to the Audiolarm II series. Designed for panel mounting, this internally driven indicator operates on a DC input voltage range of 5 to 25 volts. It generates an acoustic signal at a frequency of 2.9 kHz with a sound pressure level of 70 dB measured at 5 volts and a distance of 61 cm. The device draws a power current between 5 and 25 mA. Physical dimensions include a diameter of 1.410 inches (35.81 mm) and a maximum installation height of 1.480 inches (37.59 mm). It features wire leads for termination and is rated IP68 for dust tightness and waterproofing. Operating temperatures range from -20°C to 65°C, and it holds UL and UR approval.

Feature Summary

• Internally driven piezoelectric chime mechanism
• IP68 rated for dust tight and waterproof protection
• Panel mount design with top port location
• UL and UR agency approved

Applications

• Industrial control panel signaling
• Equipment status indication
• Alarm systems requiring water-resistant components

Procurement Notes

Verify the specific suffix (F) against official datasheets to confirm lead wire specifications. Ensure the operating voltage aligns with the 5-25V DC range. Confirm IP68 rating requirements match environmental conditions. Check UL/UR listing numbers for compliance needs. Validate physical dimensions for panel cutout compatibility.

Selection Notes

Select this component when a durable, waterproof chime is required for panel mounting. The wide voltage range allows flexibility in system design. Consider the 70 dB SPL for audible alerts in moderate noise environments. Verify temperature ratings for extreme cold or heat applications. Compare dimensions against available panel space constraints.

Part Context
