CPT-1495CI-300

Alarms, Buzzers, And Sirens Overview

The CPT-1495CI-300 is an externally driven piezoelectric transducer buzzer manufactured by Same Sky. It features a 14.00 mm diameter and 10.50 mm height, designed for through-hole mounting with wire leads. The component operates at a nominal voltage of 10 V, drawing 12 mA current, and produces a sound pressure level of 84 dB at 10V measured at 10 cm. Its resonant frequency is 4.25 kHz, and it supports a maximum voltage range up to 30 V. The unit offers IP67 protection against dust and water ingress.

Alarms, Buzzers, And Sirens Feature Summary

• IP67 waterproof and dustproof housing for harsh environments
• Externally driven piezoelectric transducer design
• Through-hole termination with wire leads

Alarms, Buzzers, And Sirens Applications

• Industrial equipment audio signaling
• Waterproof electronic enclosures
• Harsh environment alarm systems

Alarms, Buzzers, And Sirens Procurement Notes

Verify the specific lead type configuration when ordering, as the suffix 'CI' denotes wire leads compared to other variants like PC pins. Confirm that the application circuit provides the required 10 V drive signal to achieve the specified 84 dB output. Ensure mechanical clearance allows for the 14 mm diameter and 10.50 mm height dimensions within the target assembly.

Alarms, Buzzers, And Sirens Selection Notes

Select this model for applications requiring robust environmental sealing combined with high-volume wave soldering compatibility. The externally driven nature requires an external oscillator circuit, distinguishing it from self-exciting buzzers. Consider the 4.25 kHz frequency for optimal audibility in noisy industrial settings where higher frequencies might be masked.

Alarms, Buzzers, And Sirens Part Context

This component belongs to the CPT series of piezoelectric audio indicators from Same Sky (formerly CUI Devices). The series includes various mounting styles and voltage ratings. The CPT-1495CI-300 specifically targets industrial sectors needing reliable, sealed acoustic signaling solutions that can withstand exposure to moisture and particulate matter without performance degradation.

Alarms, Buzzers, And Sirens Replacement Considerations

Direct substitutes include the CPT-1495C-300, which shares identical electrical and dimensional specifications but utilizes custom wire leads instead of standard pin terminations. Verify that any replacement maintains the IP67 rating and 10 V operating voltage to ensure functional equivalence in existing designs.
