HCM1612GP3.6K-R

RYD HCM1612GP3.6K-R is a Dual-Tone Passive Electromagnetic Buzzer with Φ16×14mm dimensions, producing two discrete frequencies (1600Hz and 2100Hz) only when driven by corresponding external square-wave signals; no internal oscillator or logic is present. Output level is 85dB at each frequency when driven at 12V nominal amplitude. Acceptable drive amplitude range is 6–18Vp-p. Tonal differentiation for hierarchical alert signaling is achieved entirely through external driver frequency switching. Rated −40 to +85°C. Suited to automotive dashboard warnings, industrial safety systems, and medical equipment where dual-tone capability without additional components is required. Customization available: frequency pair selection and parameter adjustment per application requirement.
