Wire Attach Option

When you use a rugged WR sensor from MaxBotix® Inc., the sensor pin out is exposed allowing you to attach wires and equipment to the sensor. While leaving the pin out open provides greater flexibility in how you choose to connect to the sensors, it can leave the sensors exposed to the weather in some applications. If your mounting requires you to protect the back of the sensor from damage, you must seal the sensor pin out against rain and other potential hazards. For users that want to purchase a fully sealed sensor, the wire attach option is a great choice.

Protected Environment Sensor

When choosing an ultrasonic sensor it is very important to be aware of the surrounding environment. This is a key factor and the first consideration when selecting a sensor. This requires looking around the environment that your sensor will be exposed to which can be as simple as the outdoor elements or as complicated as the type of people or animals that will be in the environment with the sensor.

MaxSonar-WR Cube Corner Reflector Performance

Sometimes when using an ultrasonic sensor, users experience detection of unwanted objects that appear outside the expected beam pattern. These types of detections are the result of reflectors present in the environment. Corner reflectors can be surprisingly small, yet present a large reflection back to the sensor.

Some examples of common corner reflectors follow: a book shelf along a wall, a curb in a parking lot, a 1/2” wide seam in a concrete floor, internal bracing in a bin, or the inside corner of a doorway in a narrow hall. Each of these examples can create a corner reflector that may cause unwanted detections.
