Overview of the C4000 Standard Safety Light Curtain

The C4000 Standard is a safety light curtain from SICK, designed to safeguard hazardous points on machinery such as pinch points, processing areas, or access zones. The device operates on the optoelectronic principle, consisting of a sender and receiver that create an invisible protective field. Any intrusion by a person or object into this field triggers the safety outputs (OSSD) to stop the machine immediately.

Resolution: 14, 20, 30 or 40 mm (for finger, hand, or arm detection)
Protective field height: 300 – 1,800 mm
Scanning range: Up to 19 m (for resolutions of 20 mm and above)
Protection rating: IP65, operating temperature 0 °C to +55 °C
Outputs: 2 PNP OSSD, 24 V DC supply
