Features of the weather-resistant MB7051, XL-MaxSonar-WRML, include centimeter resolution, short to long-distance detection, range information from 50cm to 1041cm to the target with the largest acoustic return, a 5.1Hz read rate, and various output options: pulse-width, analog voltage, and RS232 serial.

The MB7051 from the XL-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.

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

The MB7051 is ideal for applications requiring small or soft target detection range at longer ranges than our other XL-MaxSonar-WR sensors. This is our most sensitive ultrasonic sensor in the XL-MaxSonar-WR line of sensors and is designed for pencil beam applications >10º, environments with acoustic and electrical noise, people detection, soft targets, bin level measurement, and tank level measurement.

In addition, the MB7051 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.


Models with additional chemical resistance are available

The F-Option (IP68) design modification provides our weather resistant sensors with extra protection against corrosive chemical environments. Ask for the F-Option (IP68) when ordering.

Chemical Compatibility

Product 3D Models


800 Housing (Extended Horn)

Significantly improve the resistance to galvanic corrosion.

Wire Attachment Length for Distributors change to 3ft

The color of any exposed epoxy will be black or gray, rather than only gray.

MaxBotix is changing its manufacturing process for the F-Option. The method of creating an F-Option part was changed to improve the manufacturability and decrease lead times for F-Option parts.
