  • Maximum range of 765 cm (300 inches)
  • Long range, narrow detection zone

Features of the weather-resistant MB7070, XL-MaxSonar-WRA, include centimeter resolution, short to long-distance detection, range information from 20cm to 765cm for the nearest detectable target, a 10Hz read rate, and various output options: analog envelope, analog voltage, and RS232 serial.

The MB7070 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 (this product has multiple housing options available).

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

In addition, the MB7070 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.


Variations on this sensor model

MB7060 is the pulse-width version of this sensor.
MB7076 is the 10-meter version of this sensor.


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.

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.
