A high-performance waterproof ultrasonic distance sensor with an enclosed probe, capable of measuring distances from 270 mm to 8000 mm. Based on ultrasonic echo ranging, it determines distance by measuring the time between sending a pulse and receiving the echo — no physical contact required.

Suitable for detecting a wide range of materials including transparent objects, metals, non-metals, liquids, solids, and powders. The bell-mouth shell design improves directivity and output stability.
