Maxbotix XL-MaxSonar-EZ4 Sonar Range Finder MB1240

SKU : MXL-MS-EZ4SRFMB1240

This ultrasonic (sonar) range finder features real-time automatic calibration and noise rejection resulting in virtually noise-free distance readings even in environments with changing acoustic and electrical noise. The sensor detects objects from 0 to 7.65 m (25 ft) and has a resolution of 1 cm (0.4") for distances beyond 20 cm (8"). The XL-MaxSonar works from 3.3 to 5V and peaks at only 0.5 W of power consumption.The EZ0 / AE0, EZ1 / AE1, EZ2 / AE2, EZ3 / AE3, and EZ4 / AE4 versions have progressively narrower beam angles.

Overview

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.
