The XL-MaxSonar-EZ series has high power output along with real-time auto calibration for
changing conditions (temperature, voltage and acoustic or electrical noise) that ensure you
receive the most reliable (in air) ranging data for every reading taken. The XL-MaxSonar-EZ/AE sensors have a low power
requirement of 3.3V – 5.5V and operation provides very short to long-range detection and ranging, in a tiny and compact form factor.
The MB1200 and MB1300 sensor series detects objects from 0-cm1 to 765-cm (25.1 feet) or 1068cm (35 feet) (select models) and
provide sonar range information from 20-cm2 out to765-cm or 1068-cm (select models) with 1-cm resolution. Objects from 0-cm1 to
20-cm2,3 typically range as 20-cm2,3. The interface output formats included are pulse width output (MB1200 series), real-time analog
voltage envelope (MB1300 series), analog voltage output, and serial digital output.
1Objects from 0-mm to 1-mm may not be detected. 2For the MB1200/MB1300, MB1210/1310, MB1260/MB1360, and MB1261/MB1361, this distance is 25-cm. 3Please see Close Range Operation

Close Range Operation
Applications requiring 100% reading-to-reading reliability should not use MaxSonar sensors at a distance closer than
20cm. Although most users find MaxSonar sensors to work reliably from 0 to 20cm (25cm select models) for detecting
objects in many applications, MaxBotix® Inc. does not guarantee operational reliability for objects closer than the
minimum reported distance. Because of ultrasonic physics, these sensors are unable to achieve 100% reliability at close
distances.

XL-MaxSonar® - EZ/AE™ Series
Real-time Noise Rejection
While the XL-MaxSonar® is designed to operate in the presence of noise, best operation is obtained when noise strength is
low and desired signal strength is high. Hence, the user is encouraged to mount the sensor in such a way that minimizes
outside acoustic noise pickup. In addition, keep the DC power to the sensor free of noise. This will let the sensor deal
with noise issues outside of the users direct control (in general, the sensor will still function well even if these things are
ignored). Users are encouraged to test the sensor in their application to verify usability.
For every ranging cycle, individual filtering for that specific cycle is applied. In general, noise from regularly occurring
periodic noise sources such as motors, fans, vibration, etc., will not falsely be detected as an object. This holds true even
if the periodic noise increases or decreases (such as might occur in engine throttling or an increase/decrease of wind
movement over the sensor). Even so, it is possible for sharp non-periodic noise sources to cause false target detection. In
addition, *(because of dynamic range and signal to noise physics,) as the noise level increases, at first only small
targets might be missed, but if noise increases to very high levels, it is likely that even large targets will be missed.
*In high noise environments, if needed, use 5V power to keep acoustic signal power high. In addition, a high acoustic noise
environment may use some of the dynamic range of the sensor, so consider a part with less gain such as the MB1220/MB1320
MB1230/MB1330 or MB1240/MB1340. For applications with large targets, consider a part with ultra clutter rejection like the
MB7369.

XL-MaxSonar® - EZ/AE™ Series
Independent Sensor Operation
The XL-MaxSonar-EZ sensors have the capability to operating independently when the user desires. When using the
XL-MaxSonar-EZ sensors in single or independent sensor operation, it is easiest to allow the sensor to free-run. Free-run
is the default mode of operation for all of the MaxBotix Inc., sensors. The XL-MaxSonar-EZ sensors have three separate
outputs that update the range data simultaneously: Analog Voltage, Pulse Width, and RS232 Serial. Below are diagrams
on how to connect the sensor for each of the three outputs when operating in a single or independent sensor operating
environment.
_____________________________________________________________________________________________________________________________________
Selecting a XL-MaxSonar-EZ/AE
Different applications require different sensors. The XL-MaxSonar-EZ/AE product line offers varied sensitivity to allow
you to select the best sensor to meet your needs.

The diagram above shows how each product balances sensitivity and noise tolerance. This does not effect the maximum
range, pin outputs, or other operations of the sensor. To view how each sensor will function to different sized targets
reference the XL-MaxSonar-EZ Beam Patterns.

Beam Characteristics
Background Information Regarding our Beam Patterns
Each XL-MaxSonar-EZ sensor has a calibrated beam pattern. Each sensor is matched to provide the
approximate detection pattern shown in this datasheet. This allows end users to select the part
number that matches their given sensing application. Each part number has a consistent field of
detection so additional units of the same part number will have similar beam patterns. The beam
plots are provided to help identify an estimated detection zone for an application based on the
acoustic properties of a target versus the plotted beam patterns.
Each beam pattern is a 2D representation of the detection area of the sensor. The beam pattern is
actually shaped like a 3D cone (having the same detection pattern both vertically and horizontally).
Detection patterns for dowels are used to show the beam pattern of each sensor. Dowels are long
cylindered targets of a given diameter. The dowels provide consistent target detection characteristics
for a given size target which allows easy comparison of one MaxSonar sensor to another MaxSonar
sensor.
People Sensing:
For users that
desire to detect
people, the
detection area to
the 1-inch
diameter dowel, in
general, represents
the area that the
sensor will
reliably detect
people.
For each part number, the four patterns (A, B, C, and D) represent the detection zone for a given
target size. Each beam pattern shown is determined by the sensor’s part number and target size.
The actual beam angle changes over the full range. Use the beam pattern for a specific target at any given distance to
calculate the beam angle for that target at the specific distance. Generally, smaller targets are detected over a narrower
beam angle and a shorter distance. Larger targets are detected over a wider beam angle and a longer range.
