avoid accidents, personal injury, and material damage.
DANGER!
… indicates a situation of imminent danger, which will
lead to a fatality or serious injuries if not prevented.
WARNING!
… indicates a potentially dangerous situation, which may
lead to a fatality or serious injuries if not prevented.
CAUTION!
… indicates a potentially dangerous situation, which may
lead to minor/slight injuries if not prevented.

2 Safety
2.1 Intended use
The DS35 and DT35 distance sensors are opto-electronic sensors for per-
forming non-contact distance measurement of objects.
The DL35 and DR35 distance sensors are opto-electronic sensors for per-
forming non-contact distance measurement on reective tape.
SICK AG assumes no liability for losses or damage arising from the use of

4.2 Function
The DS35 and DT35 distance sensors are opto-electronic sensors for per-
forming non-contact distance measurement of objects.
The DL35 and DR35 distance sensors are opto-electronic sensors for per-
forming non-contact distance measurement on reective tape.
If Q1 and Q2 are used as switching outputs, the following operation modes
are available: Distance to Object (DtO), Window (Wnd), and Object between
Sensor and Background (ObSB). The measured distance value can be
transferred cyclically over IO-Link.
For the DT35 and DL35 models, the Q2 output can be congured as a cur-
rent output (4 … 20 mA), voltage output (0 … 10 V), or switching output.
