Selecting a HRLV-MaxSonar-EZ

Different applications require different sensors. The HRLV-MaxSonar-EZ product line offers varied sensitivity to allow

you to select the best sensor to meet your needs.

The diagram above shows how each product balances sensitivity and noise tolerance. This does not affect the maximum

range, pin outputs, or other operations of the sensor. To view how each sensor will function to different sized targets

reference the HRLV-MaxSonar-EZ-Beam Patterns.

Beam Patterns

Background Information Regarding our Beam Patterns

Each HRLV-MaxSonar-EZ sensor has a calibrated beam pattern. Each sensor is matched to provide

the approximate detection pattern shown in this datasheet. This allows end users to select the part

number that matches their given sensing application. Each part number has a consistent field of

detection so additional units of the same part number will have similar beam patterns. The beam

plots are provided to help identify an estimated detection zone for an application based on the

acoustic properties of a target versus the plotted beam patterns.

Each beam pattern is a 2D representation of the detection area of the sensor. The beam pattern is

actually shaped like a 3D cone (having the same detection pattern both vertically and horizontally).

Detection patterns for dowels are used to show the beam pattern of each sensor. Dowels are long

cylindered targets of a given diameter. The dowels provide consistent target detection characteristics

for a given size target which allows easy comparison of one MaxSonar sensor to another MaxSonar

sensor.

For each part number, the four patterns (A, B, C, and D) represent the detection zone for a given target size. Each beam

pattern shown is determined by the sensor’s part number and target size.

The actual beam angle changes over the full range. Use the beam pattern for a specific target at any given distance to

calculate the beam angle for that target at the specific distance. Generally, smaller targets are detected over a narrower

beam angle and a shorter distance. Larger targets are detected over a wider beam angle and a longer range.
