TXO-86-515-W

Overview

The TXO-86-515-W is a piezoelectric chime alarm manufactured by Floyd Bell Inc. It features an internally driven indicator circuit and accepts DC input within a voltage range of 5 to 25 volts. The device operates at a frequency of 2.9 kHz with a sound pressure level of 70 dB measured at 5 volts and 61 cm distance. Power consumption ranges from 5 to 25 mA across the specified voltage range. Designed for panel mounting, it includes wire leads for connection and offers IP68 protection against dust and water ingress. The unit functions reliably in operating temperatures between -20°C and 65°C.

Feature Summary

• Internally driven piezoelectric chime mechanism
• IP68 rated for dust tightness and waterproofing
• Wide DC voltage compatibility from 5V to 25V

Applications

• Panel mount chime alarms
• Industrial status indicators
• Waterproof environmental monitoring systems

Procurement Notes

Verify the specific part number suffix against official Floyd Bell documentation to ensure correct voltage and acoustic specifications. Confirm that the wire lead termination style matches the installation requirements. Check for UL or UR agency approval markings if safety certification is required for the intended application environment.

Selection Notes

Select this component when a self-contained, internally driven audible indicator is needed for harsh environments requiring high ingress protection. Ensure the available DC supply voltage falls within the 5 to 25 V range. Consider the 70 dB SPL output relative to ambient noise levels and the 2.9 kHz tone frequency for audibility requirements.

Part Context

This model belongs to the Floyd Bell Audiolarm II series of piezoelectric chimes. These devices are designed for direct DC drive without external oscillators. The series typically offers various mounting options and acoustic outputs tailored for industrial signaling and alarm applications where reliability and environmental sealing are critical.

Replacement Considerations

Consult official Floyd Bell cross-reference lists for verified substitutes. Generic replacements may not match the IP68 rating or internal drive characteristics.
