MB7052 XL-MaxSonar-WRM1
High Performance Ultrasonic Precision Rangefinder 

MB7052 XL-MaxSonar-WRM1 Ultrasonic Rangefinder Product Description

The XL-MaxSonar-WRM1 ignores smaller targets and only reports the range to target with the largest acoustic return. This is one of our advanced weather resistant sensors designed for target detection and ranging outdoors or in tank or bin applications.

The weather resistant XL-MaxSonar-WRM1 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.
