CEM-1612

Overview

The CEM-1612 is a sealed, externally driven magnetic audio transducer buzzer manufactured by Same Sky. It features a 16 mm round housing with a 14 mm depth and utilizes through-hole mounting for PCB integration. The device operates at a rated voltage of 12 V with a typical current consumption of 40 mA. It produces a sound pressure level of 85 dB at 12 V and 10 cm distance, or 97 dB peak-to-peak. The operating frequency is 2.048 kHz, and the unit supports an operating voltage range of 6.0 to 18.0 V.

Feature Summary

• Externally driven magnetic design requiring external oscillator circuitry
• Sealed construction for environmental protection
• Through-hole mounting for secure PCB attachment

Applications

• Industrial control panel indicators
• Appliance status signaling
• Security system alerts

Procurement Notes

Verify exact specifications against the official product datasheet before procurement. Confirm that the application circuit provides the necessary external drive signal, as this is an externally driven unit. Ensure mechanical dimensions fit the enclosure constraints. Check supply chain availability through authorized distributors.

Selection Notes

Select this component when a high-intensity audible alert is required in industrial or consumer applications. The 16 mm diameter offers a balance between acoustic output and board space. Consider the need for external driving circuitry compared to self-excited alternatives. Verify voltage compatibility within the 6.0 to 18.0 V range.

Part Context

This part belongs to the Same Sky CEM series of electromagnetic signallers. The series includes various sizes and voltage ratings. The CEM-1612 specifically denotes the 16 mm diameter variant with 12 V nominal operation. It is designed for reliable performance in standard ambient conditions.

Replacement Considerations

Check for direct substitutes from the Same Sky CEM series with matching 16 mm dimensions and 12 V rating. Verify pinout compatibility if replacing on existing boards. Ensure equivalent sound pressure levels are maintained for regulatory compliance.
