SICK C40S Series Light Curtain, 1.03m Protective Height, 24V Supply Voltage - C40S-0904CA010

This light curtain is a safety sender designed for industrial environments to protect personnel and machinery by detecting intrusions into a guarded zone. It operates from a 24V supply and uses optical synchronisation for emitter-receiver pairing, supporting long-range monitoring. The device is intended for integration with safety relay systems and can be deployed where defined protective fields are required.

Features and Benefits:

• 21m scanning range provides extended monitoring distance
• 40mm beam resolution permits coarse object detection over area
• Type 4 safety classification ensures high-level risk reduction
• SIL 3 and PL e achieve stringent functional safety targets
• Optical synchronisation reduces cross-talk between units

Applications

• Suitable for machine guarding on production lines
• Used with safety relays for restart interlock functions
• Ideal for guarding long conveyor sections
• Can be used for access protection in automated cells
• Used with external device monitoring and bypass schemes

What environmental limits affect its installation?

It operates between 0°C and +55°C and withstands non‑condensing humidity of 15%-95%.

How is the device physically constructed for mounting?

The housing is an extruded aluminium profile with a 48mm x 40mm cross-section and specific sliding‑nut grooves for side mounting.

What electrical connection and protection class apply?

It requires a 24V DC supply (19.2V to 28.8V range) and meets Protection Class III requirements.

What failure behaviour is defined for safety outputs?

On fault at least one OSSD is driven to the OFF state to ensure a safe condition.
