There are two detection methods with the LR-Z and these methods are why it's considered the do-it-all sensor. Additional features are also highlighted below to further explain how different this series is.
The LR-Z Series provides uncompromised detection ability by automatically adjusting its sensitivity using the Light Power Control function. Built-in background and foreground suppression also aid in stable detection, regardless of color or angle.
This function detects all conditions except the “reference” state, which allows detection of any target, regardless of surface or shape variations, and even in cases when the laser light does not return to the sensor.
This innovative feature expands the detection capabilities of the LR-/ZB250AP sensors beyond that of the normal DATUM mode. I-DATUM combines the stability of distance based detection with the sensitivity of received light intensity. By using a stable background as a reference surface, I-DATUM can be used to reliably detect transparent and translucent targets by recognising small changes in the received light quantities returned to the sensor.
