MB7051 XL-MaxSonar-WRML

High Performance Ultrasonic Precision Rangefinder

Product Description

Features of the weather resistant MB7051, XL-MaxSonar-WRML, include centimeter resolution, short to long distance detection, range information from 25cm 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 which 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.
