HCM1205X

RYD HCM1205X is an Active Electromagnetic Buzzer with Φ12×9.5mm dimensions, 5V DC rated operation, and 88dB continuous tone output at 2300Hz. This Active Electromagnetic Buzzer features a built-in driver circuit producing immediate audible output from a simple two-wire DC connection, providing 3dB above standard 85dB models for additional sound-pressure margin against enclosure attenuation, protective grilles, or elevated ambient noise. Operating voltage range is 4–7V with 30mA maximum current, ensuring stable performance across regulated and unregulated 5V supplies. PBT housing with red copper leads and tin plating. Rated −30 to +70°C. Suited to industrial equipment behind protective covers, IP-rated consumer electronics, and automotive interior alerts where acoustic loss through barriers requires compensating output. Customization available: ingress protection level and new model development for volume orders requiring enhanced SPL.
