The Yujie KQ-200KH-2 is a high-precision ultrasonic transducer specifically designed for robotics, position tracking, and industrial distance measurement applications. Operating at 200 kHz ± 3%, this transducer features an ultra-narrow 7° ± 2° beamwidth, delivering exceptional directional accuracy for focused ultrasonic detection across a 12 cm to 2 m range.
Engineered with a durable aluminum alloy housing and IP65 protection rating, the KQ-200KH-2 withstands harsh industrial environments while maintaining precise performance from -20°C to 70°C. Its compact design (Ø19 × 11 mm), simple 7mm contact pin connection, and minimal 10g weight make it ideal for easy integration into robots, automated guided vehicles (AGVs), flow measurement systems, traffic monitoring equipment, and manufacturing automation. The short dead zone enables close-range detection, while the 500V maximum working voltage ensures reliable operation in demanding industrial applications.
