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.

About Ultrasonic Sensors
Our ultrasonic sensors are in air, non-contact object detection and ranging sensors that detect objects within an area. These
sensors are not affected by the color or other visual characteristics of the detected object. Ultrasonic sensors use high
frequency sound to detect and localize objects in a variety of environments. Ultrasonic sensors measure the time of flight
for sound that has been transmitted to and reflected back from nearby objects. Based upon the time of flight, the sensor
then outputs a range reading.

Pin Out
Pin 1-BW-Leave open (or high) for serial output on the Pin 5 output. When Pin 1 is held low the Pin 5 output sends a
pulse (instead of serial data), suitable for low noise chaining.
Pin 2-PW– For the MB1200 (EZ) sensor series, this pin outputs a pulse width representation of range. To calculate
distance, use the scale factor of 58uS per cm.
For the MB1300 (AE) sensor series, this pin outputs the analog voltage envelope of the acoustic wave form. The output
allows the user to process the raw waveform of the sensor.
Pin 3-AN– For the 7.6 meter sensors (all sensors except for MB1260, MB1261, MB1360, and MB1361), this pin outputs
analog voltage with a scaling factor of (Vcc/1024) per cm. A supply of 5V yields ~4.9mV/cm., and 3.3V yields ~3.2mV/
cm. Hardware limits the maximum reported range on this output to ~700cm at 5V and ~600cm at 3.3V. The output is
buffered and corresponds to the most recent range data.
For the 10 meter sensors (MB1260, MB1261, MB1360, MB1361), this pin outputs analog voltage with a scaling factor of
(Vcc/1024) per 2 cm. A supply of 5V yields ~4.9mV/2cm., and 3.3V yields ~3.2mV/2cm. The output is buffered and
corresponds to the most recent range data.
Pin 4-RXThis pin is internally pulled high. The XL-MaxSonar-EZ sensors will continually measure range and output
if the pin is left unconnected or held high. If held low the will stop ranging. Bring high 20uS or more for range reading.
Pin 5-TX- When Pin 1 is open or held high, the Pin 5 output delivers asynchronous serial with an RS232 format, except
voltages are 0-Vcc. The output is an ASCII capital “R”, followed by three ASCII character digits representing the range
in centimeters up to a maximum of 765, followed by a carriage return (ASCII 13). The baud rate is 9600, 8 bits, no parity,
with one stop bit. Although the voltage of 0-Vcc is outside the RS232 standard, most RS232 devices have sufficient
margin to read 0-Vcc serial data. If standard voltage level RS232 is desired, invert, and connect an RS232 converter such
as a MAX232.
When Pin 1 is held low, the Pin 5 output sends a single pulse, suitable for low noise chaining (no serial data).
Pin 6-+5V- Vcc – Operates on 3.3V - 5V. The average (and peak) current draw for 3.3V operation is 2.1mA (50mA
peak) and at 5V operation is 3.4mA (100mA peak) respectively. Peak current is used during sonar pulse transmit.
Pin 7-GND- Return for the DC power supply. GND (& V+) must be ripple and noise free for best operation.
