Mitsumi introduces SU series ultrasonic sensors for use in the car
The SU series of ultrasonic sensors from Mitsumi Electronics is designed for use in automotive applications, offering reliable support for a wide range of vehicle operations. These bi-directional sensors are built to withstand extreme environmental conditions, operating efficiently within a temperature range of -40°C to 85°C. With a nominal frequency of 40kHz, they provide accurate and consistent performance in various driving scenarios.
Each sensor features a sound pressure level of 100dB, ensuring strong signal output even in noisy environments. The capacitance is specified at 1.650pF with a tolerance of ±20%, allowing for flexibility in different circuit designs. The sensitivity of -84dB ensures high responsiveness, while the minimum reflection sensitivity of 1.5mVp-p guarantees that even small objects can be detected effectively.
Additionally, the maximum return time of 1.5ms allows for quick response and efficient data processing, making these sensors ideal for applications such as parking assistance, proximity detection, and obstacle avoidance systems. Whether used in passenger cars or commercial vehicles, the SU series offers a robust and versatile solution for modern automotive electronics.
