MaxBotix Inc., products are engineered and assembled in the USA.
Base sensor (MB7360 and MB7380)
The MB7360 and MB7380 are the base model of the HRXL-MaxSonar-WR sensor line. These sensors are recommended for users
unsure of which sensor to use in their application. All other sensors in this series are based off of these sensor models. The additional
features are mentioned in their respective sections below.
_______________________________________________________________________________________________________________________________________
HRXL-MaxSonar-WRLS (MB7363 and MB7383)
The HRXL-MaxSonar-WRLS sensors are 10 meter sensors with a higher sensitivity than other HRXL-MaxSonar-WR products. This
sensor is recommended for applications in which objects do not reflect enough ultrasonic sound, such as people, to be detected. Users
are encouraged to test the sensor in their application to verify usability.

HRXL-MaxSonar-WRL (MB7366, MB7386)
The HRXL-MaxSonar-WRL sensors are the 10-meter version of the HRXL-MaxSonar-WR sensors.

HRXL-MaxSonar-WRML (MB7368, MB7388)
The HRXL-MaxSonar-WRML 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 with a 10-meter maximum range. (The sensor will also reject
periodic noise, even noise that has a higher amplitude than the acoustic return from the target.) This provides the flexibility to
consistently range larger targets in the presence of clutter and noise. If the largest target is removed, the HRXL-MaxSonar-WRML
will switch to the target with the next largest detectable return.
The HRXL-MaxSonar-WRML sensors were designed for applications where users were concerned with ranging the distance to large
flat targets (such as in a water tank). This stands in contrast to other HRXL-MaxSonar-WR sensors which will report the distance to
the first detectable target.
In general, the HRXL-MaxSonar-WRML will select the largest target from its field of view and report its range. Even so, objects up
close may provide significantly greater returns over distant objects. Users are encouraged to test the sensor in their application to
verify usability.
When targets are of similar amplitude reflections, preference is given to the closest target.

HRXL-MaxSonar-WRM (MB7369 and MB7389)
The HRXL-MaxSonar-WRM sensors are the 5-meter version of the HRXL-MaxSonar-WRML sensors.

HRXL-MaxSonar-WRB (MB7375 and MB7395)
The HRXL-MaxSonar-WRB sensors are the 1.525-meter (5-foot) wide beam versions of HRXL-MaxSonar-WRML sensors.

About Package Types
The HRXL-MaxSonar-WR sensors are available in a variety of packages for applications with specific mounting requirements. The
full horn package provides peak accuracy and sensitivity in this sensor line. It is recommended that testing is completed to ensure that
the selected sensor will operate as desired in your application.
Package Types Currently Available
Full Horn – 3/4” NPT straight; back mounted thread
Compact – 3/4” NPT straight; back mounted thread
1”NPS – External thread over full sensor body (1”NPS)
1”BSPP – External thread over full sensor body (1”BSPP)
30mm1.5 – External thread over full sensor body (30mm1.5)
Extended Horn – 3/4” NPT straight; back mounted thread. Enhanced detection of
distant and small targets.
All package types have exposed PCB on user end for easy connection. Users
desiring a fully enclosed assembly may purchase the “Shielded Cable Attach
Option” along with their sensor.
