The weather resistant HRXL-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.

The HRXL-MaxSonar-WRLST MB7383 ultrasonic sensor features a maximum range of 10 meters to large targets. The MB7383 is our most sensitive long range sensor.

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

The MB7363 is the RS232 version of this sensor.
The MB7380 is the 5 meter version of this sensor.

Models with additional chemical resistance are available
The F-Option design modification provides our weather resistant sensors with extra protection against corrosive chemical environments. Ask for the F-Option when ordering.
