Detects short and wide zone
The Maxbotix MB7375 HRXL-MaxSonar-WRB Weather Resistant Ultrasonic Range Finder is a rugged, ultrasonic sensor component module. This outdoor sensor provides wide-angled detection and ranging out to five feet 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-WRB MB7375 ultrasonic sensor features a maximum range of 5 feet (1525 mm). The MB7375 is our sensor with the widest detection zone. 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. HRXL-MaxSonar-WR sensor has a calibrated beam pattern. Each sensor is matched to provide the approximate detection pattern shown in this datasheet. This allows end users to select the part number that matches their given sensing application. Each part number has a consistent field of detection so additional units of the same part number will have similar beam patterns.
