SICK C40S Series Light Curtain, 900mm Protective Height, 24V Supply Voltage - C40S-0903CA010

This light curtain is a safety sensor designed for industrial environments to monitor access points and stop hazardous machine movements. It operates as the sender unit within an optically synchronised pair and is intended for integration into safety circuits where a Type 4 safety light curtain is required. The module supports configurable scanning ranges and communicates with compatible safety relays for controlled enabling and deactivation of outputs.

Features and Benefits:

• 30mm beam resolution for precise object detection
• 21m maximum scanning distance for long-range protection
• Type 4 safety level delivering high fault-tolerant operation
• 24V supply voltage enabling standard industrial power integration
• Compact 40mm width light curtain module for tight installations

Applications

• Suitable for safeguarding access to automated assembly lines
• Ideal for perimeter protection in material handling systems
• Used with safety relays for machine enabling and interlock functions
• Can be used for palletiser protection in packaging plants

What environmental conditions can it withstand?

It is rated to operate between 0°C and +55°C and is protected to IP65 against dust and water ingress.

How is synchronisation between sender and receiver achieved?

Synchronisation is optical, ensuring coordinated beam timing between units for correct detection.

What safety performance classifications apply to the unit?

It meets SIL3, Category 4 and PLe safety standards according to relevant IEC and ISO tests.

What electrical connection options are provided for installation?

The device uses a straight cable connection with conductor cross-section 0.75mm² and supports cable lengths up to 50m depending on load and supply.
