Contrast
Detects intensity changes due to variation
in surface finish, tone, or lightness

Minimum Object Separation (MOS)
The minimum distance a target must be from the
background to be reliably detected by a sensor.
A MOS of 5 mm means the sensor can detect an
object that is at least 5 mm from the background.
Excess Gain
Excess gain is a measure of the minimum light energy needed
for reliable sensor operation. Higher excess gain allows the
sensor to detect darker objects at steeper angles.
Excess gain can be expressed as the following formula.
Excess gain = Light energy falling on receiver element/
sensor’s amplifier threshold
The threshold is the level of sensing energy required by
the sensor's amplifier to cause the sensor's output to
switch "ON" or "OFF."
