CEM-1201(50)

Overview

The CEM-1201(50) is a magnetic buzzer from the Same Sky CEM series, designed for through-hole mounting. It operates at a rated voltage of 1.5 V with a current consumption of 40 mA. The device produces a single-tone sound at a frequency of 2.4 kHz. Acoustic performance includes a sound pressure level of 80 dB measured at 1.5 V and 10 cm distance. The unit features PC pin termination and has a cylindrical diameter of 12.00 mm with a maximum installation height of 10.00 mm. It supports an input type of zero-to-peak signal and functions within a temperature range of -20°C to 60°C.

Feature Summary

Magnetic transducer technology for external driver circuits
Single-tone acoustic output generation
Through-hole PCB mounting with top ported terminals
Washable construction suitable for standard manufacturing processes

Applications

Electronic appliance status indicators
Simple alarm systems
Consumer electronics audio alerts
Industrial control panel signaling

Procurement Notes

Verify the specific suffix designation against official documentation to confirm exact acoustic tolerances and lead time requirements. Confirm RoHS compliance status and moisture sensitivity level prior to integration into production workflows. Ensure driver circuitry matches the specified 1.5 V rating and 40 mA current draw to prevent component damage or performance deviation.

Selection Notes

Select this component when a low-voltage, through-hole magnetic buzzer is required for simple audible signaling. The 12 mm form factor suits compact enclosures. Verify that the application environment remains within the -20°C to 60°C operating range. Consider the external drive requirement and ensure the controlling circuit can supply the necessary peak current without exceeding the rated specifications.

Part Context

This part belongs to the Same Sky CEM series of magnetic buzzers. These components utilize a permanent magnet and diaphragm assembly driven by an external oscillator circuit. The series offers various voltage and size options for different acoustic power requirements while maintaining a standardized through-hole footprint for easy PCB layout integration.
