SICK C20S-075103D51 Sensor
SICK C20S-075103D51 safety light curtain unit, part 1085116. Protective field monitoring for machine guarding applications.
Overview
The SICK C20S-075103D51 (part number 1085116) is a unit of the C20S safety light curtain series. It monitors a protective field for machine guarding applications, opening the safety output circuit when the field is interrupted, as part of a matched sender-receiver system.
How It Works
As part of a safety light curtain pair, the unit participates in a synchronized infrared beam grid across the protective field. When the grid is interrupted by a person or object, the safety outputs switch off and the machine control executes the safe stop.

Frequently Asked Questions
Is the C20S still the right choice for new projects?
For new designs, current families such as C4-RD or deTec offer the latest features; C20S serves existing installations and replacements.
What does the 0751 in the order code indicate?
The order code encodes the field configuration of this C20S variant; confirm exact field height and resolution in the datasheet.
Which safety controller fits?
Standard safety relays and controllers such as the UE410 family evaluate the curtain outputs.
