Maxbotix Weather-Resistant Ultrasonic Rangefinder

Take your sonar outside - great for all-weather robots! The XL-MaxSonar-WRMA1 ignores smaller targets and only reports the range to target with the largest acoustic return. This is our most advanced weather-resistant sensor designed for target detection and ranging outdoors or in tank or bin applications.

The weather-resistant XL-MaxSonar-WRMA1 is a rugged ultrasonic sensor component module. This outdoor sensor provides very short to long-distance detection and ranging in a compact, robust PVC housing. The ultrasonic sensor meets the IP67 water intrusion standard and matches standard electrical 3/4‑inch PVC pipe fittings.

High output acoustic power combined with continuously variable gain, real‑time background automatic calibration, real‑time waveform signature analysis, and noise rejection algorithms results in virtually noise-free distance readings. This holds true even in the presence of many of the various acoustic or electrical noise sources. The XL‑MaxSonar-WR sensors are factory calibrated to match narrow sensor beam patterns and provide reliable long-range detection zones.
