2.4.1. Sensor front

The TOF sensor measure the distance to object by emissing small pulses of IR-laser light and then measure the
time for the light, reflected by an object, to return to the sensor.

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 10 ... 2000 [mm]*.
* It is not recommended to use settings higher than maximum 1000 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.
Sensor
Two point mode
The switching information changes when the measurement value passes the threshold defined in setpoint
SP1. This change occurs only with rising measurement values. The switching information also changes when
the measurement value passes the threshold defined in setpoint SP2. This change occurs only with falling
measurement values. Hysteresis is not considered in this case.
