MAXBOTIX MB7138 XL-TrashSonar-WRM Ultrasonic Sensor maxbotix Sonar

The MAXBOTIX MB7138 XL-TrashSonar-WR Ultrasonic Sensor operates by emitting high-frequency sound waves and measuring the time it takes for the echo to return after bouncing off an object. This time delay is used to calculate the distance to the object. The sensor features real-time auto-calibration to adjust to changing conditions such as voltage sag, acoustic noise, and electrical noise.

• Avoid Extreme Conditions: Do not expose the sensor to conditions beyond its operating temperature range of 40°C to 70°C.,
• Prevent Water Intrusion: Despite its IP67 rating, avoid submerging the sensor unless absolutely necessary and ensure all seals are intact.,
• Ignore Maintenance: Regularly check and recalibrate the sensor as needed to ensure optimal performance.

• Check Compatibility: Ensure the sensor is compatible with your system requirements and operating voltage (3.0V to 5.5V).,
• Use Appropriate Mounting: Use the MB7950 Mounting Hardware for secure installation.,
• Consider Environmental Conditions: Utilize the sensor's weather-resistant features for outdoor applications.

• Description: The sensor can detect objects from 0-cm to 350-cm, with reliable sonar range information from 20-cm to 350-cm. Objects closer than 20-cm will typically register as 20-cm.

• Description: The sensor's operating temperature range is from 40°C to 70°C. Operating outside this range can affect the sensor's accuracy and longevity.

• Description: The sensor operates within a voltage range of 3.0V to 5.5V. Operating outside this range can lead to improper functioning or damage.

• Description: The sensor provides multiple output options including pulse-width, analog voltage, and RS232 serial. Choose the output that matches your application requirements and connect accordingly.

• Description: Connect the sensor's power lines to a suitable power source within the 3.0V to 5.5V range. Ensure polarity is correct to avoid damage.

The sensor has an outer diameter of 44 mm, a length of 70 mm, and a nut size of 26 mm. It weighs 50 grams, with shipping dimensions of 9 × 6 × 6 cm and a shipping weight of 0.055 kg.
