Mitsumi unveils new ultrasonic sensors for in-vehicle apps

The SU series of ultrasonic sensors from Mitsumi Electric Co. Ltd were developed to target in-vehicle applications to address the growing need for providing information from outside the vehicle and for vehicle operation assistance.

Rated for operation between the -40°C and 85°C temperature range, the bidirectional sensor features a 40kHz nominal frequency, 100dB (typ) sound pressure, 1,650pF ±20 percent capacitance, -84dB (typ) sensitivity, 1.5mVp-p (min) reflection sensitivity and 1.5ms (max) reverberating time.

Members of the SU series have an external dimension of 15(?)-by-10mm; however, added Mitsumi, it can be adjusted to 14(?)-by-20mm in diameter.
