- 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
