HCM1212BX

RYD HCM1212BX is an Active Electromagnetic Buzzer with Φ12×7.5mm compact-height dimensions, 12V DC rated operation, and 85dB continuous tone output at 3000Hz. This Active Electromagnetic Buzzer features a built-in driver circuit that eliminates the need for an external oscillator; a simple two-wire DC connection produces immediate audible output. Operating voltage range is 9–15V DC with 30mA maximum current, matching automotive and industrial 12V supply rails. The 7.5mm reduced profile fits slim assemblies where standard-height buzzers exceed available clearance. PBT housing with red copper leads and tin plating. Rated −30 to +70°C. Suited to automotive cabin electronics, industrial micro-modules, and infrastructure panels where 12V operation and height constraint are simultaneous requirements. Customization available: parameter tuning and waterproof/dustproof rating per application environment.
