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 assistance in a variety of vehicle operations. These bi-directional sensors are built to perform efficiently under extreme environmental conditions, with an operating temperature range from -40°C to 85°C. Each sensor operates at a nominal frequency of 40kHz, producing a sound pressure level of 100dB, making it suitable for detecting objects in various driving scenarios.
With a capacitance of 1.650pF ±20% and a sensitivity of -84dB, the SU series ensures accurate and consistent performance. The minimum reflection sensitivity is as low as 1.5mVp-p, allowing the sensor to detect even small objects or subtle changes in the environment. Additionally, the maximum return time is limited to 1.5ms, ensuring fast response times that are critical for real-time applications such as parking assistance, obstacle detection, and automated driving systems.
These features make the SU series an ideal choice for automotive engineers looking for robust and high-performance ultrasonic sensors that can withstand harsh conditions while delivering precise and reliable data. Whether used in advanced driver-assistance systems (ADAS) or basic proximity sensing, the SU series offers a versatile solution for modern vehicle designs.
