2.4.1. Sensor front
The Diffuse Reflective sensor emits light towards a target and measures the light level reflected from the target.
Once the energy of the received light level exceed a predefined level then the sensor switches the output. The
sensing distance depends on the colour, shape and structure of the target.
2.4.1.1. SSC (Switching Signal Channel)
For presence (or absence) detection of an object in front of the face of the sensor, the following settings are
available: SSC1 or SSC2. Setpoints can be set from 100 ... 1 000 [mm]*.
* It is not recommended to use settings higher than maximum 1 000 mm however under optimal conditions
(object surface, ambient light environment and EMC noise etc.) the distance can be set at higher value.
2.4.1.2. Switchpoint mode:
Each SSC channel can be set operate in 3 modes or be disabled. The Switchpoint mode setting can be
used to create more advanced output behaviour. The following switchpoint modes can be selected for the
switching behaviour of SSC1 and SSC2
Disabled
SSC1 or SSC2 can be disabled individually.
Single point mode
The switching information changes, when the measurement value passes the threshold defined in setpoint
SP1, with rising or falling measurement values, taking into consideration the hysteresis.
