Features
• I2C bus communication allows rapid
control of multiple sensors with only
two wires
• High acoustic power output
• Real-time auto calibration and noise
rejection for every ranging cycle
• Calibrated beam patterns
• Continuously variable gain
• Object presence information as close
as 1-mm from the sensor. Range
information starting at min. distance.
• 3V to 5.5V supply with very low
average current draw
• Readings can occur up to every 25mS
(40Hz rate)
4
for up-close objects.
15Hz rate for full range.
• Triggered operation provides a new
range reading as desired
• Ultrasonic signal frequency of 42KHz
• Status pin available to determine
sensor state
• Power-up address reset pin available
• Physical dimensions match other
XL-MaxSonar-EZ products
• Operational temperature from
0°C to +65°C (32F to +149F)

Low Power Requirement
• Wide, low supply voltage
requirements eases battery powered
design
• Low current draw reduces current
drain for battery operation
• Fast first reading after power-up
eases battery requirements
Benefits
• Acoustic and electric noise resistance
• Reliable and stable range data
• Low cost
• Quality controlled beam
characteristics
• Very low power rangefinder,
excellent for multiple sensor or
battery based systems
• Ranging is triggered externally
• Fast measurement cycle
• No power up calibration required
• Perfect for when objects may be
directly in front of the sensor during
power up
• Easy mounting
Applications and Uses
• Multi-sensor arrays
• Proximity zone detection
• People detection
• Robot ranging sensor
• Autonomous navigation
• Educational and hobby robotics
• Environments with acoustic and
electrical noise
• Distance measuring
• Long range object detection
• Security systems
• Motion detection
• Landing flying objects
• Collision avoidance
• Bin level measurement
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 for detecting objects from 0 to 20cm 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.

The I2CXL-MaxSonar-EZ series offers industrial ultrasonic sensors with an easy to
use I2C interface. These sensors have a high acoustic power output along with
real-time auto calibration for changing conditions (voltage and acoustic or electric
noise) that ensure users receive the most reliable (in air) ranging data for every reading taken. The low power
3V – 5.5V operation provides very short to long-range detection and ranging, in a compact form factor. The
I2CXL-MaxSonar-EZ detect objects from 0-cm* to 765-cm (25.1 feet) and provide sonar range information
from 20-cm or 25-cm out to 765-cm with 1-cm resolution. Objects from 0-cm* to minimum distance typically
range as minimum distance.
