HCM1203UX-2700

RYD HCM1203UX-2700 is an Active Electromagnetic Buzzer with Φ12×7.5mm dimensions, 3.3V DC rated operation, and 85dB continuous tone output at 2700Hz, featuring ≤50ms response time. 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. The ≤50ms response time supports precise timing in pulsed-alert patterns and synchronized multi-device notification schemes. Operating voltage range is 2–5V with 30mA maximum current. The 7.5mm height provides a lower profile than standard 9.5mm variants while maintaining full-rated output. Rated −30 to +70°C. Suited to industrial safety systems, medical device alarms, and consumer electronics where alert latency directly impacts user response time and vertical clearance is limited. RoHS compliant materials. Customization available: parameter adjustment and connection interface options.
