CT31P-30W520-1

Alarms, Buzzers, And Sirens Overview

The CT31P-30W520-1 is an externally driven piezoelectric transducer manufactured by Challenge Electronics. It features a flange panel mount design with wire leads and a connector. The device operates at a resonant frequency of 5.2 kHz and produces a sound pressure level of 120 dB when driven at 18 V. Electrical characteristics include a current draw of 10 mA and a peak-to-peak voltage rating of 30.0 V. The physical dimensions are 31.6 mm in diameter and 8.5 mm in height.

Alarms, Buzzers, And Sirens Feature Summary

• Externally driven piezoelectric technology for single-tone operation
• Flange panel mount configuration with integrated wire leads and connector
• High acoustic output capability with specified decibel rating at rated voltage

Alarms, Buzzers, And Sirens Applications

• Industrial alarm systems requiring high-decibel audible alerts
• Electronic equipment status indicators
• Panel-mounted warning devices in control cabinets

Alarms, Buzzers, And Sirens Procurement Notes

Verify the specific connector type and wire length requirements against the system interface before procurement. Confirm that the driving circuit can supply the required 10 mA current at the operating voltage. Ensure the mounting hole diameter matches the 31.6 mm flange specification to guarantee proper fit and acoustic sealing. Check for RoHS compliance documentation if environmental regulations apply to the final assembly.

Alarms, Buzzers, And Sirens Selection Notes

Select this component when a high-output, single-frequency audible indicator is required for panel mounting. The externally driven nature allows for flexible signal generation from microcontrollers or oscillators. Consider the 120 dB output level for environments requiring loud alerts over background noise. The flange mount simplifies installation compared to screw-mount alternatives.

Alarms, Buzzers, And Sirens Part Context

This part belongs to the Challenge Electronics CT31P series of piezoelectric buzzers. The series offers various diameters and frequencies. The CT31P designation indicates a 31.6 mm diameter unit. The suffix W typically denotes wire lead configuration. This model is distinct from internally driven buzzers as it requires an external AC signal source.

Alarms, Buzzers, And Sirens Replacement Considerations

Direct replacements must match the 31.6 mm diameter, 8.5 mm height, and 5.2 kHz resonant frequency. Verify that substitute parts support the same 30 Vpp input and provide comparable 120 dB output at 18 V. Ensure the mounting flange geometry and connector type are compatible with existing panel cutouts and wiring harnesses.
