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-cm

to 765-cm (25.1 feet) or 1068cm (35 feet) (select models) and

provide sonar range information from 20-cm

out to765-cm or 1068-cm (select models) with 1-cm resolution. Objects from 0-cm

20-cm

2,3

typically range as 20-cm

2,3

. 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.

Objects from 0-mm to 1-mm may not be detected.

For the MB1200/MB1300, MB1210/1310, MB1260/MB1360, and MB1261/MB1361, this distance is 25-cm.

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 XL-MaxSonar®- EZ™ Series High Performance Sonar Range Finder MB1200, MB1210, MB1220, MB1230, MB1240, MB1260, MB1261 MB1300, MB1310, MB1320, MB1330, MB1340, MB1360, MB13618 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.
PAGE 2
XL-MaxSonar® - EZ/AE™ Series 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.
PAGE 3
XL-MaxSonar® - EZ/AE™ Series Sensor Minimum Distance The sensor minimum reported distance is 20cm1 (7.87 inches). However, the XL-MaxSonar-EZ will range and report targets to the front sensor face. Large targets closer than 20cm1 will typically range as 20cm1. Sensor Operation from 6-inches to 20-inches Because of acoustic phase effects in the near field, objects between 20cm and 50cm may experience acoustic phase cancellation of the returning waveform resulting in inaccuracies.

XL-MaxSonar® - EZ/AE™ Series Voltage vs Temperature The graph below shows minimum operating voltage of the sensor verses temperature. MaxBotix® Inc.

PAGE 5
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.
PAGE 6
XL-MaxSonar® - EZ/AE™ Series Sensor Timing Diagrams Power Up Timing Sensor Free-Run Timing Real-Time Operation Timing Description 175mS after power-up, the XL-MaxSonar is ready to begin ranging. If Pin-4 is left open or held high (20uS or greater), the sensor will take a range reading. The XL-MaxSonar checks the Pin-4 at the end of every cycle. Range data can be acquired once every 99mS. Each 99mS period starts by Pin-4 being high or open, after which the XL-MaxSonar calibrates and calculates for 20.
PAGE 7
XL-MaxSonar® - EZ/AE™ Series Using Multiple Sensors in a single system When using multiple ultrasonic sensors in a single system, there can be interference (cross-talk) from the other sensors. MaxBotix Inc., has engineered a solution to this problem for the XL-MaxSonar-EZ sensors. The solution is referred to as chaining. We have 3 methods of chaining that work well to avoid the issue of cross-talk. The first method is AN Output Commanded Loop.
PAGE 8
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.
PAGE 9
XL-MaxSonar® - EZ/AE™ Series MB1200/MB1300: XL-MaxSonar-EZ/AE0 The XL-MaxSonar-EZ/AE0 is the highest sensitivity and widest beam sensor of the XL-MaxSonar-EZ/AE sensor series. The wide beam makes this sensor ideal for a variety of applications including people detection, autonomous navigation, and wide beam applications. Note: All sensors sold after Oct 01, 2013 have a minimum reported distance of 25cm. All sensors sold before this date have a 20cm minimum reported distance.
PAGE 10
XL-MaxSonar® - EZ/AE™ Series MB1210/MB1310: XL-MaxSonar-EZ/AE1 The XL-MaxSonar-EZ/AE1 has slightly less sensitivity and narrower beam than the MB1200/MB1300 sensors. This makes the MB1210/MB1310 an ideal sensor for applications in which the MB1200/MB1300 are too sensitive. Note: All sensors sold after Oct 01, 2013 have a minimum reported distance of 25cm. All sensors sold before this date have a 20cm minimum reported distance.
PAGE 11
XL-MaxSonar® - EZ/AE™ Series MB1220/MB1320: XL-MaxSonar-EZ/AE2 The XL-MaxSonar-EZ/AE2 is the recommended sensor for users unsure of which XL-MaxSonar-EZ/AE sensor to use. This sensor balances sensitivity and detection to targets of different sizes. This sensor is a good comprise between sensitivity and side object rejection.
PAGE 12
XL-MaxSonar® - EZ/AE™ Series MB1230/MB1330: XL-MaxSonar-EZ/AE3 The XL-MaxSonar-EZ/AE3 is a narrow beam, and is slightly more sensitive then the MB1240/MB1340.
PAGE 13
XL-MaxSonar® - EZ/AE™ Series MB1240/MB1340: XL-MaxSonar-EZ/AE4 The XL-MaxSonar-EZ/AE4 is the least sensitive and narrowest beam pattern in the XL-MaxSonar-EZ/AE sensor series. This makes the senor great for applications in which there is a large amount of acoustic. The MB1240/MB1340 sensor is also recommended in applications where only large target detection is required.
PAGE 14
XL-MaxSonar® - EZ/AE™ Series MB1260/MB1360: XL-MaxSonar-EZ/AEL0 The XL-MaxSonar-EZL/AEL0 has the same gain and sensitive as the MB1200/MB1300. This sensor features a longer range of 1068cm to large targets. This sensor is recommended for long range measurement to large targets. Note: Firmware rev 1.6b and newer have a 25cm minimum reported distance. This applies to all sensors sold after February 20, 2013. All sensors sold before this date have a 20cm minimum reported distance.
PAGE 15
XL-MaxSonar® - EZ/AE™ Series MB1261/MB1361: XL-MaxSonar-EZL/AEL1 The XL-MaxSonar-EZL/AEL1 is the long range version of the MB1210/MB1310 ultrasonic sensor. This sensor features a longer maximum range of 1068cm to large targets. This sensor is recommended for applications in which the MB1210/ MB1310 do not have a long enough detection distance.
