Optimized for automotive reversing systems and safety robotics, this 48kHz ultrasonic transducer features a precision-engineered asymmetric beam (110° Horizontal / 45° Vertical). Its unique fan-shaped detection zone provides panoramic bumper coverage to eliminate side blind spots, while the narrow vertical angle effectively rejects ground clutter—preventing false alarms common in low-mounted sensors. With a blind zone reduced to just 20cm (≤1.2ms ringing time) and a rugged IP67 waterproof housing, it delivers reliable collision avoidance performance in rain, snow, or tight parking maneuvers.
