  • MB7389 HRXL-MaxSonar-WRMT MaxBotix Ultrasonic Sensor

    Ranges from 300mm to 5000mm with a 6.7Hz read rate. Pulse-width, analog voltage, and TTL serial. Reports range to the largest target.

    The MB7389 HRXL-MaxSonar-WRMT ignores smaller targets and only reports the range to target with the largest acoustic return. This is Maxbotix most advanced weather resistant sensor designed for target detection and ranging outdoors or in the tank or bin applications.

    Housing Option Available: (Specify in order note)

    • 3/4" NPS WR Housing
    • 3/4" NPS WRC Compact Housing
    • 1" NPS Housing 
    • 1" BSPP Housing 
    • 30MM 1.5 Housing

    The HRXL-MaxSonar-WRMT sensors are equipped with filtering firmware which allows the sensor to ignore smaller targets and noise, and still report the target that gives the largest acoustic return. (The sensor will also reject periodic noise, even noise that has a higher amplitude than the acoustic return from the target.) This gives users the flexibility to consistently range larger targets in the presence of clutter and noise. If the largest target is removed from the field of view, the HRXL-MaxSonar-WRMT will switch to the target that gives the next largest detectable return.

    The Most-Likely filter is designed to report the distance to the largest acoustic return while ignoring smaller targets. When targets are of similar amplitude reflections, preference is given to the closest target.

    MB7380 is the standard TTL version of this sensor line.
    MB7369 is the RS232 version of this sensor.

    Models with additional chemical resistance are available

    The F-Option design modification provides Maxbotix weather resistant sensors with extra protection against corrosive chemical environments. Ask for the F-Option when ordering.
