HCM1212APB

RYD HCM1212APB is a Wide-Temperature Passive Electromagnetic Buzzer with Φ12×9mm dimensions, requiring external 2400Hz square-wave drive to produce 85dB output across −40 to +85°C ambient range. NORYL housing maintains dimensional and acoustic stability over the full specified temperature span without derating. Coil rated for 12V nominal drive; acceptable drive amplitude range is 6–15Vp-p, covering automotive and industrial rail tolerances including cold-crank and load-dump transients. Suited to automotive body electronics, industrial control cabinets, and outdoor infrastructure where extended temperature operation is a verified environmental condition. Manufactured under RYD ISO9001 quality system with RoHS compliant materials.
