Maxbotix XL-MaxSonar-EZ4 Sonar Range Finder MB1240
The Maxbotics XL-MaxSonar family of sonar range finders offers very short- to long-range
detection and ranging in an incredibly small package with low power consumption.
The XL-MaxSonar detects objects from 0 to 7.65 meters (25 feet) and provides
sonar range information beyond 20 cm (8") with a resolution of 1 cm resolution (0.4 in).
Objects between 0 and 20 cm range as 20 cm. An efficient transformer uses 0.5 W
of power to drive the transducer, yielding high-output acoustic power.
This acoustic power, combined with continuously-variable gain, real-time automatic
calibration, real-time waveform signature analysis, and real-time noise rejection algorithms,
results in virtually noise-free distance readings for most applications,
even in the presence of various acoustic or electrical noise sources.
The XL-MaxSonar distance sensor is available in five factory-calibrated beam patterns (EZ/AE0-4).
For a less-expensive, lower-resolution, shorter-range version, please consider the LV-MaxSonar-EZ family of distance sensors.
