XL-MaxSonar®-WRC™ Sensor Line
Our industrial outdoor ultrasonic sensor component module
The industrial outdoor XL-MaxSonar-WRC sensors have a compact PVC housing designed to meet IP67 water intrusion which allows the sensors to be used in applications where our standard XL-MaxSonar-WR sensors might not work. Users who can afford the size and weight limitations of the horned larger units above are encouraged to select one of the XL-MaxSonar-WR sensors.
The XL-MaxSonar-WRC sensors provide short to long distance detection and ranging with a narrow beam pattern. The XL-MaxSonar-WRC outdoor ultrasonic sensors have high power output, noise rejection, auto calibration, and factory calibrated beam patterns. Users should select a sensor with their outputs of choice and reading filtering that matches their application. Models are available with analog voltage output, serial digital output, pulse width output (select models), & real-time analog envelope output (select models).

Different applications require different sensors. The XL‑MaxSonar‑WRC series of outdoor rangefinders offer a variety of features allowing users to select the best sensor to meet their needs.
The table above shows features that exist in each of the products. To view how each sensor will function to different sized targets reference the XL‑MaxSonar‑WRC Beam Patterns.
The Difference Between XL-MaxSonar-WRC and XL-MaxSonar-WRCA
The XL-MaxSonar-WRC sensors have pulse width output.
The XL-MaxSonar-WRCA sensors have analog envelope output. The AE output allows for easy troubleshooting and is also suitable for users who wish to do advanced signal processing.
Both the XL-MaxSonar-WRC product line and the XL-MaxSonar-WRCA product line offer users the serial and analog voltage distance outputs.
The Difference Between XL-MaxSonar-WR and XL-MaxSonar-WRC
Sensors from the XL-MaxSonar-WR product line offer better overall performance but have a larger size. These are our recommended outdoor products except when their size or weight become a limitation.
Sensors from the XL-MaxSonar-WRC product line offer a more compact housing for use in applications where there are mounting or weight restrictions.

Weather Resistant (IP67) Sensors, and Optional Chemical Resistance
The industrial outdoor XL-MaxSonar-WRC sensors have a compact PVC housing designed to meet IP67 water intrusion which allows the sensors to be used in applications where our standard XL-MaxSonar-WR sensors might not work. Users who can afford the size and weight limitations of the horned larger units above are encouraged to select one of the XL-MaxSonar-WR sensors.
The XL-MaxSonar-WRC sensors provide short to long distance detection and ranging with a narrow beam pattern. The XL-MaxSonar-WRC outdoor ultrasonic sensors have high power output, noise rejection, auto calibration, and factory calibrated beam patterns. Users should select a sensor with their outputs of choice and reading filtering that matches their application. Models are available with analog voltage output, serial digital output, pulse width output (select models), & real-time analog envelope output (select models).
In addition to the standard XL-MaxSonar-WR, MaxBotix Inc. has developed the F-Option for additional protection necessary in a few hazardous chemical environments. Extremely corrosive gases or liquids can degrade or compromise the operation of the sensing unit. As a result, we offer a more chemically inert seal which allows our sensors to operate in all but the harshest of chemical environments. In addition to the chemical resistance the sensor has improved performance in wet or dust environments.
Standard Weather Resistant Models
The exposed materials of a properly mounted XL-MaxSonar-WR sensor are: Aluminum (oxidized surface), PVC, & silicone rubber (VMQ).
F-Option
The exposed materials of a properly mounted XL-MaxSonar-WR sensor with the F-Option added are: Aluminum (oxidized surface), PVC, & Flourosilicone (with an additional back up FEP Teflon® seal).
Additional Considerations
To ensure long term operation of the sensor, terminal connections should not be exposed to water, dust, or other chemicals. Follow proper mounting when installing your sensor. This is easily accomplished using standard PVC pipe fittings which match the provided mounting threads (3/4" National Pipe Thread Straight) MB7950 Mounting hardware can be purchased along with your sensor.
Sensors are designed for operation in air, but may work well in many gases. Testing for proper operation is encouraged. Compensation for speed of sound changes in other gases should be applied to sensor output, this is often accomplished through a simple 2 point linear calibration.
Rugged & Reliable Outdoor Ultrasonic Sensors
The industrial XL‑MaxSonar‑WR products are the highest quality for cost outdoor ultrasonic sensors on the market. They provide an industrial component module solution that offers easy to use outputs, weather & dust resistance, no sensor dead zone, calibrated narrow beam patterns, stable range readings, low power demands, and a host of other features detailed in the product datasheets.
The XL-MaxSonar-WR sensors represent an industry revolution which has already found use in a number of advanced or industrial solutions where ultrasonic sensors have not been historically considered a viable solution due to unstable readings, high cost, and high power requirements.
The Noise Filtering
The sensor dynamically adjusts its sensitivity to compensate for outside electrical & acoustic noise sources.
The Interface
The XL‑MaxSonar‑WR interface was designed to be very easy and intuitive to use. The interface output formats included are pulse width output, analog voltage output, and asynchronous serial digital output. All interfaces work without user code or complicated setup strings.
The Power Requirements
The XL‑MaxSonar‑WR functions throughout a 3.0V to 5.5V operational voltage range. This allows for easy integration at either 3.3V or 5V and means that users of low voltage microcontrollers, or those who wish to operate in solar or battery based systems do not have to provide an extra power supply for the sensor.
The XL‑MaxSonar‑WR sensors have a 3.4mA average current draw during free ranging operation.
The Controlled Narrow Beam Shape
Similar ultrasonic products may have frequent side lobe detection and can even falsely trigger on objects behind or to the sides of the sensor. The XL‑MaxSonar‑WR offers a controlled narrow beam that is designed to reject small objects (clutter) outside of the central beam area and provides long range sensitivity without detecting frivolous or unwanted targets.
The Calibration
Each XL‑MaxSonar‑WR is tested for proper operation at our facility and comes with a factory calibrated narrow beam pattern to help ensure consistent operation of the sensor even from part to part.
The XL‑MaxSonar‑WR automatically calibrates to its environment before every range reading. This calibration includes compensation for voltage, humidity, acoustic noise, and electrical noise conditions. Temperature compensation for speed of sound changes are not applied.
The Price
This sensor is designed to be sold in volume. As a result, our customers benefit from our large production volumes and distributed engineering expenses.

Custom Solutions
For some of our customers our standard products have not fit the requirements of their particular application. As a result, we have designed and manufactured a number of custom solutions. Some of the product improvements and features have been incorporated directly into our standard products. For other users we have evaluated their specifications and charged a small NRE fee for their custom parts.
Contact MaxBotix Inc. with your application and its requirements and our engineers will work to arrive at a desirable solution.
