Ultrasonic Depth Sounder Transducer 200 kHz Marine Sonar | HJ200KH-P
The Yujie HJ200KH-P is a compact and cost-effective depth sounder transducer, specifically designed for small vessels, underwater positioning, and depth measurement in seas, rivers, and lakes. Operating at 200 kHz ± 5% with a powerful 250W rated RMS power output, this transducer ensures exceptional high-speed performance up to 55 knots (63 MPH) while minimizing turbulence noise with its streamlined plastic housing. Featuring a 13° beamwidth and quality factor of 13, it delivers precise echo sounding with 155 dB transmission response and -181 dB reception response. The circular PZT element (Ø27 mm) provides reliable depth detection with 900 pF free capacitance and 1.2 kΩ parallel impedance. With a lightweight 400g design and 2-meter cable, it's perfect for recreational fishing boats, small yachts, and marine exploration applications requiring accurate depth measurement in various water conditions.
