HCM1201X

RYD HCM1201X is an Active Electromagnetic Buzzer with Φ12×9.5mm dimensions, 1.5V DC rated operation, and 80dB continuous tone output at 2300Hz, drawing only 20mA maximum current. This Active Electromagnetic Buzzer features a built-in driver circuit producing immediate audible output from a simple two-wire DC connection, extending battery life by consuming one-third to one-half the current of standard 30mA-class alternatives. The 1.2–3V operating range covers single-cell alkaline and lithium primary battery discharge curves without boost conversion. PBT housing with red copper leads and tin plating. Rated −30 to +70°C. Suited to battery-operated consumer electronics, wearable health monitors, and disposable medical devices where ultra-low current draw governs component selection. Manufactured under RYD ISO9001 quality system using RoHS compliant materials.
