This sensor allows the user to measure the distance from the center position of sensor to the beam element. The beam element is the nearest to the center position of the sensor in the direction and range of the sensor.

Figure 2 Definition of Output Value of Distance Sensor
First, the sensor finds the closest point of sheet from the sensor center position. And a position of sheet is checked whether the position is in the range of sensor. If the position is in the sensor, the distance from sensor center to sheet on sensing direction is computed. As shown in Figure 2, if a sheet body passes to the range of the sensor, the sensor output can be computed from the following equation.
where,
: the result of sensor. (Output
Value)
: the position of the closest point
of sheet body on the direction and in the range of the sensor.
: the position of sensor center.
: the specified direction of the
sensor.
: the minimum distance from sensor
center to mid plane of sheet.

Note
If the computed distance(Output value) is greater than sensor range, the result is zero.
The value of Distance Sensor is negative if there is the center of sensor into the sheet segment.
