Features of the weather-resistant MB7480, 4-20HR-MaxSonar-WRI, include millimeter resolution, short to long-distance detection, range information from 500mm to 5000mm for the nearest detectable target, a 7.5Hz read rate, and the industry-standard 20-4mA output where 20mA is minimum range and 4mA is maximum range.

The MB7480 from the 4-20HR-MaxSonar-WR line of outdoor sensors is a rugged ultrasonic sensor component module. This sensor comes in a compact and robust PVC housing that meets the IP67 water intrusion standard and matches standard electrical 3/4‑inch PVC pipe fittings (this product has multiple housing options available).

The 4-20HR-MaxSonar-WR sensors are factory calibrated to match narrow sensor beam patterns and provide reliable long-range detection zones.

In addition, the MB7480 offers virtually noise-free distance readings through the use of high-output acoustic power combined with continuously variable gain, real‑time background automatic calibration, real‑time waveform signature analysis, and noise rejection algorithms. This holds true even in the presence of many of the various acoustic or electrical noise sources.
