HCM1205APA

RYD HCM1205APA is a Low-Frequency Passive Electromagnetic Buzzer with Φ12×9mm dimensions, requiring external 2048Hz square-wave drive to produce 85dB output. NORYL housing provides thermal and chemical resistance for demanding assembly environments. Coil rated for 5V nominal drive; acceptable drive amplitude range is 3–8Vp-p. The 2048Hz fundamental frequency produces a deeper tonal character distinguishable from higher-frequency alerts in multi-signal systems. Suited to industrial control panels, automotive interior modules, and medical equipment where tonal differentiation supports hierarchical alert prioritization. Manufactured under RYD ISO9001 quality system with RoHS compliant materials.
