SICK miniTwin4 Series Light Curtain 1 Twin-Stick, 14 mm Resolution

This miniTwin4 light curtain is a twin-stick safety sensor designed to protect access points on machinery by creating a multi-beam protective field. It operates as a standalone device or as the last unit in cascaded systems and provides optical synchronisation without separate wiring. The device is intended for industrial machine-guarding applications where a Compact protective height and a short-to-medium scanning distance are required.

• 14mm beam resolution reduces sensing gaps for small-object detection
• 4 to 5m scanning distance allows mid-range safeguarding of work zones
• 14ms response time enables Rapid system reaction to interruptions
• 24V supply with 5-pin M12 connector supports standard control integration
• Type 4 safety classification provides high-level risk reduction

• Suitable for guarding loading and unloading stations on conveyors
• Ideal for presence detection at robotic cell openings
• Used with safety relays for dual-channel stop circuitry
• Can be used for access protection on assembly machines
• Suitable for short-range perimeter monitoring in packaging lines

It operates from 24V DC within a permitted range of 19.2V DC to 28.8V DC.

Outputs are dual PNP OSSD semiconductors with short-circuit protection and cross-circuit monitoring.

It is rated to IP65 and operates between -20°C and +55°C with non-condensing humidity.

It is supplied as a twin-stick with C-Fix and L-Fix brackets, system plug and a test rod corresponding to the resolution.
