Narrowest beam of the HRLV-MaxSonar-EZ sensors
Best for large object detection applications

Features of the MB1043, HRLV-MaxSonar-EZ4, include millimeter resolution, the narrowest beam width of any sensor in the HRLV-MaxSonar-EZ sensor line, short to long distance detection, range information from 300mm to 5000mm, a 10Hz read rate, and various output options: pulse-width, analog voltage, and a choice of either RS232 or TTL serial.

The MB1043 is a great choice for applications where only larger objects need to be detected.

The MB1043 from the HRLV-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 MB1043 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.
