MB7139 XL-TrashSonar-WR MaxBotix Ultrasonic Sensor

MB7139 XL-TrashSonar-WR MaxBotix Ultrasonic Sensor

Ranges from 20cm to 350cm with a 10Hz read rate. Pulse-width, analog voltage, and RS232 serial. Reports range to the closest target.

Features of the weather resistant MB7139, XL-TrashSonar-WR, include centimeter resolution, short to mid-distance detection, range information from 20cm to 350cm for the nearest detectable target, a 10Hz read rate, and various output options: pulse-width, analog voltage, and RS232 serial.

The MB7139 from the XL-TrashSonar-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 (this product has multiple housing options available).

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

In addition, the MB7139 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.
