The CMS-30205-124L40-67 is a compact miniature speaker designed for applications requiring sealed, waterproof audio output. It features an IP67 rating for front-side protection, a rated power of 1.2 W (maximum 1.5 W), and an impedance of 4 O at 1.5 kHz. The speaker delivers a sound pressure level of 95 dB typical at 1.5 W measured 10 cm away, with a frequency response spanning from its resonant frequency (850 Hz typical) to 20 kHz. The device incorporates a neodymium-iron-boron magnet, PBT frame, and PEN cone material, operating reliably across -30°C to +65°C. Its compact dimensions of 30.0 × 20 × 5.0 mm and 40 mm lead wire with Molex connector make it ideal for portable electronics, alarm systems, and sealed enclosure applications where durability and space efficiency are essential.
