4-20HR-MaxSonar-WRMI MB7489 Waterproof Ultrasonic Distance Sensor (50~500cm, IP67)

The MB7489 4-20HR-MaxSonar-WRMI sensor excels in diverse environmental conditions with its millimeter resolution and reliable 7.5Hz read rate. Built for both short and long-distance detection, it accurately measures distances ranging from 500mm to 5000mm. The sensor's industry-standard 20-4mA output signifies that 20mA represents the minimum range and 4mA denotes the maximum range, ensuring precise readouts for users.

Encased in a durable PVC housing, the sensor aligns with IP67 water intrusion standards, making it suitable for wet environments. Its design accommodates standard electrical 3/4-inch PVC pipe fittings, providing versatility in installation. With various housing options available, it seamlessly fits into a range of operational setups.

Factory-calibrated for excellence, the 4-20HR-MaxSonar-WR sensors are engineered to offer dependable long-range detection. This ensures they maintain a narrow sensor beam pattern. The MB7489 is adept at focusing on the largest acoustic return and can differentiate between multiple similar reflections, favoring the nearest target. This specificity makes it invaluable in environments cluttered with varied noise.

In the dynamic landscape of tank and bin applications, the sensor's ability to switch to the next largest detectable return when the primary target is removed showcases its adaptability. Its advanced filtering capabilities position it as a top choice for scenarios where consistently accurate detection is crucial.

Featuring high-output acoustic power, the MB7489 delivers virtually noise-free distance readings. Its strength comes from a combination of continuously variable gain, real-time background automatic calibration, real-time waveform signature analysis, and sophisticated noise rejection algorithms. These features work harmoniously to combat diverse acoustic or electrical noise, ensuring seamless operation.
