Murata offering a new ultrasonic sensor for automotives to see around the vehicle
Sensor and electronics component technology expert Murata has unveiled a new ultrasonic sensor device for automotive applications. The new MA48CF15-7N features high-sensitivity and rapid responsiveness and is packed in a hermetically-sealed package to protect against liquid ingress.
By using ultrasonic sensor higher levels of autonomy, more accurate short/medium-range object detection mechanisms can be achieved in autonomous driving vehicles. These sensors emit ultrasonic waves and sense the reflected waves to detect object presence and also reads the distance of the object. Ultrasonic sensors find more use in detecting nearby objects and help in building parking assistant systems. A couple of ultrasonic sensors are placed on the rear part of the car/vehicle to detect an obstacle few meters away. MA48CF15-7N is designed to detect objects in the distant range of 15cm to 550cm with high obstacle detection accuracy by throwing ultrasonic beam across an angle of 120° by 60°. The 1100pF±10% capacitance (at 1kHz) is another important aspect, with the narrow deviation exhibited meaning that no transformer adjustment is required. Other details shared by Murata on this product includes: The resonant frequency is 48.2±1.0kHz and there is a 35±10 Q value for improved usability plus better...
