Features of the MB1230, XL-MaxSonar-EZ3, include centimeter resolution, a narrow beam as well as excellent side object rejection, short to long distance detection, range information from 20cm to 765cm, a 10Hz read rate, and various output options: pulse-width, analog voltage, and RS232 serial.

The MB1230 has a slightly wider beam width than the MB1240 which makes it a good choice for applications where the MB1240 does not have enough sensitivity.

The MB1230 from the XL-MaxSonar-EZ line of sensors is a very small, less than one cubic inch, ultrasonic sensor component module. This sensor comes with mounting holes provided on the circuit board for easy installation in nearly all applications.

In addition, the MB1230 offers virtually noise-free distance readings through the use of high-output acoustic power combined with continuously variable gain, real‑time background automatic calibration, real‑time waveform signature analysis, and noise rejection algorithms. This holds true even in the presence of many of the various acoustic or electrical noise sources.
