CPE-121

Alarms, Buzzers, And Sirens Overview

The CPE-121 is a piezoelectric audio transducer manufactured by Same Sky, designed for industrial applications. It features a 24 mm diameter and 5 mm height panel mount form factor with wire leads. The device operates within a voltage range of 3 to 28 VDC and draws a rated current of 13 mA at its nominal 12 V rating. It produces a continuous tone at a frequency of 4.5 kHz with an acoustic output level of 83 dB.

Alarms, Buzzers, And Sirens Feature Summary

• Piezoelectric technology ensures reliable sound generation without internal driving circuits.
• Industrial-grade construction supports operation across a wide input voltage spectrum.
• Panel mount design with integrated wire leads facilitates direct enclosure integration.

Alarms, Buzzers, And Sirens Applications

• Industrial machinery status indication
• Equipment fault alarm signaling
• Control panel operational alerts

Alarms, Buzzers, And Sirens Procurement Notes

Verify the specific manufacturing date code upon receipt to ensure compliance with current RoHS directives and material specifications. Confirm that the wire lead length and termination style match the intended assembly requirements. Cross-reference the datasheet revision against the component marking to validate electrical parameters before finalizing procurement orders.

Alarms, Buzzers, And Sirens Selection Notes

Select this component when a simple, robust audible indicator is required for panel-mounted industrial equipment. The wide voltage tolerance allows flexibility in power supply design without requiring additional regulation for the buzzer circuit. Consider the 83 dB output level relative to ambient noise environments to ensure adequate audibility for safety or status notifications.

Alarms, Buzzers, And Sirens Part Context

This part belongs to Same Sky's line of piezoelectric transducers, which are distinct from electromagnetic buzzers due to their solid-state construction. The CPE series typically offers higher efficiency and lower current consumption compared to magnetic alternatives. It serves as a basic alerting component within broader audio device portfolios.
