MB7155 XL-MaxSonar-WRA

High Performance Ultrasonic Precision Rangefinder

Product Description

The XL-MaxSonar-WRA is our most popular weather resistant sensor designed for outdoor detection and ranging.

The weather resistant XL-MaxSonar-WR 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.

MB7060 is the pulse width output version of this sensor.
MB7072 is the stability filter version of this sensor.
MB7076 is an extra-long range version of this sensor.
MB7092 is an advanced filtered version of this sensor.

Models with additional chemical resistance are available

The F-Option (IP-68) design modification provides our weather resistant sensors with extra protection against corrosive chemical environments. Ask for the F-Option (IP-68) when ordering.
