NU200E18TR-2 18mm 200kHz Ultrasonic Distance Sensor - Aluminum Shell

The sensor is designed for short-range detection from 0.1 meters up to a maximum of 2 meters under ideal reflective conditions. The actual usable range can be influenced by target material, surface angle, and environmental factors like temperature and air turbulence.

A high-voltage driver circuit capable of generating a pulsed excitation signal up to 500V peak-to-peak is required to energize the piezoelectric element. The circuit must also include a sensitive receiver amplifier to detect the weak returning echo signal, which has a minimum sensitivity of -60dB.

The narrow 7° beam angle provides highly directional sensing, which minimizes false echoes from nearby objects or walls outside the primary detection path. This results in more accurate and reliable distance readings, especially in cluttered environments or when detecting small targets.

Yes, its sealed aluminum housing and wide operating temperature range from -40°C to +80°C make it suitable for demanding industrial and some outdoor applications. However, for prolonged outdoor exposure, additional protection from direct moisture ingress or UV radiation may be necessary depending on the specific conditions.
