CPT-2305-90PM

Alarms, Buzzers, And Sirens Overview

The CPT-2305-90PM is a piezo audio transducer buzzer manufactured by Same Sky. It features a 23 mm diameter and 5 mm height, designed for panel mounting with wire leads. The device operates at a rated voltage of 12 Vp-p and draws 5 mA current. It produces a sound pressure level of 90 dB at 12 V and 10 cm distance, with a resonant frequency of 4 kHz. The unit weighs approximately 300 mg and functions within an operating temperature range of -20°C to +60°C.

Alarms, Buzzers, And Sirens Feature Summary

• Externally driven piezoelectric technology for reliable acoustic signaling
• Panel mount configuration with flange and wire lead termination
• High sound output capability of 90 dB at specified distance

Alarms, Buzzers, And Sirens Applications

• Industrial control panels requiring audible alerts
• Medical equipment status indicators
• Consumer appliance warning systems

Alarms, Buzzers, And Sirens Procurement Notes

Verify the specific datasheet version for electrical tolerances and mechanical dimensions before integration. Confirm that the wire lead length and termination style match the target assembly requirements. Ensure the driving circuit can supply the required 12 Vp-p signal at 4 kHz resonance. Check environmental ratings against the operational temperature range of -20°C to +60°C.

Alarms, Buzzers, And Sirens Selection Notes

Select this component when a high-decibel audible indicator is needed for panel-mounted applications. The 23 mm form factor suits standard enclosure cutouts. Consider the externally driven nature, which requires an external oscillator or microcontroller PWM signal rather than internal drive circuitry. Compare against other Same Sky CPT series models if different mounting styles or sound levels are required.

Alarms, Buzzers, And Sirens Part Context

This part belongs to the CPT series of piezo audio transducers from Same Sky, formerly CUI Devices. The series offers various sizes and sound pressure levels for different alerting needs. The CPT-2305-90PM specifically targets applications requiring robust, high-volume audible feedback in industrial and commercial environments.

Alarms, Buzzers, And Sirens Replacement Considerations

Direct substitutes may include other 23 mm piezo buzzers with similar 90 dB output and panel mount configurations. Verify electrical compatibility, particularly the 12 Vp-p drive requirement and 4 kHz resonant frequency. Mechanical fitment must be confirmed due to potential variations in flange dimensions and wire lead lengths.
