CEM-1201S

Overview

The CEM-1201S is a magnetic buzzer from Same Sky, 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. Its acoustic output reaches 80 dB SPL when measured at a distance of 10 cm under the rated voltage conditions. The component features a round form factor with a diameter of 12.00 mm and a maximum installation height of 10.00 mm.

Feature Summary

• Utilizes magnetic technology for external driving applications
• Provides a single-tone audio alert signal
• Features top-port sound emission design
• Supports washable construction for manufacturing processes

Applications

• Electronic equipment requiring audible status alerts
• Medical devices needing reliable audio feedback
• Consumer electronics with simple tone generation needs
• Industrial control panels for operational signaling

Procurement Notes

Verify RoHS3 compliance status before integration. Confirm that the external drive circuit can supply the required 40 mA at 1.5 V. Ensure mechanical clearance accommodates the 12.00 mm diameter and 10.00 mm height. Validate that the 2.4 kHz frequency aligns with system acoustic requirements. Check for any specific handling instructions regarding the washable finish during assembly.

Selection Notes

Select this component when a low-voltage, through-hole buzzer is required. It suits designs needing a simple, externally driven tone generator. Consider the 80 dB SPL output for audibility in typical environments. The magnetic type offers straightforward interface without internal oscillators. Evaluate space constraints against the 12 mm diameter footprint.
