SDRP27P5-3232P50

RYD SDRP27P5-3232P50 Φ27mm High-Sensitivity Voice Driver for Medical Devices and Industrial Equipment. Featuring 118±3dB SPL output at 32Ω impedance (IEC318 coupler, 179mV input), this Φ27×5.5mm receiver provides exceptional voice clarity for environments where speech intelligibility is critical. Rated power is 50mW with frequency coverage from 20Hz to 5kHz and THD under 5% at 1kHz/1mW. The high sensitivity means less drive voltage is needed to achieve audible output, which benefits battery-powered medical alert systems, nurse call devices, industrial intercoms, and emergency signaling equipment. Compact 5.5mm depth allows flexible installation in both portable and fixed-mount devices. Manufactured under RYD ISO9001 quality system.
