HCM2512BP

RYD HCM2512BP is a Large-Diameter Deep-Tone Passive Electromagnetic Buzzer with Φ25×12.5mm dimensions, requiring external 1000Hz square-wave drive to produce 85dB output. The 25mm diaphragm generates a low-pitched fundamental that propagates effectively through solid structures and is less susceptible to high-frequency absorption by soft materials. Coil rated for 12V nominal drive; acceptable drive amplitude range is 8–14Vp-p. Rated −40 to +85°C. Suited to industrial machinery, warehouse signaling systems, and large-equipment enclosures where low-frequency sound transmission is advantageous. Customization available: parameter adjustment and lead wire options per customer specification.
