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-WRS (MB7334, MB7344, MB7354, MB7364, MB7374, MB7384)
The HRXL-MaxSonar-WRS series are specially designed, low-cost, rugged ultrasonic sensors for applications involving
soft targets such as snow or falling water droplets.

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

HRXL-MaxSonar-WRM (MB7369 and MB7389)
The HRXL-MaxSonar-WRM 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-WRM will switch to the target that gives the next largest detectable return.
The HRXL-MaxSonar-WRM 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-WRM 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.

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 (best performance)
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)
All package types have exposed PCB on user end for easy connection. Users
desiring a fully enclosed assembly may purchase the “Shielded Cable Option”
along with their sensor.
