HCM1612APA-92

RYD HCM1612APA-92 is a High-SPL Passive Electromagnetic Buzzer with Φ16×14mm dimensions, requiring external 2048Hz square-wave drive to achieve 92dB output. Larger diaphragm and acoustic chamber enable elevated sound pressure suitable for vehicle cabin alert systems where signal must penetrate upholstery, trim panels, and ambient road noise. Coil rated for 12V nominal drive; acceptable drive amplitude range is 9–15Vp-p. NORYL housing withstands under-dash thermal cycling. Rated −40 to +85°C. Suited to automotive interior warning systems, industrial safety equipment, and medical device enclosures where maximum audible output within a through-hole passive form factor is required. Manufactured under RYD ISO9001 quality system with RoHS compliant materials. Customization available: new model development for volume orders requiring automotive-specific validation.
