The minimum voltage for the sensor to start up is around 8 V. The nominal supply voltage is 12 V, so a DC-DC converter and a level shifter for the IO line will be required.

Operating temperature range is between -40 °C to +85 °C. The functionality (max. distance) may be reduced at extreme temperatures.

The resolution is depending on the circumstances and measurement environment. Under ideal conditions, an accuracy of about  4 mm can be reached but for the majority of scenarios about 1 cm is to be expected. 

To achive an ideal result, TDK recommends to mechanically decouple the ultrasonic sensor module from the chassis. This can be achieved by the use of a mounting supplement. Furter informations and step file proposals can be found in the product resources.

Object detection without distance measurement is possible up to 0 cm with one single module.
Object detection with distance measurement up to 2 cm is possible by usage of multiple ultrasonic sensor modules.

The speed of sound in air depends on the temperature and can be approximated as c = 331 m/s + 0.6 * T. Since the output signal of the sensor is the time of flight, the temperature should be compensated.

Heavy rain, snow or dust deposited on the membrane surface can reduce the acoustic signal which therefore can influence the measurement capability. Light rain or snowfall does not affect the measurement.

Using multiple ultrasonic sensor modules, triangulation is possible.

Currently only black color is available.

As the module is working with ultrasonic sound, a "free" view on the target is required.

The housing consists of a single piece of anodized aluminum without any joints.
