SICK L41 Series Light Beam Receiver, 1 Beam(s), 84 m Max Range

This safety single-beam sensor is a receiver intended for industrial safeguarding and presence detection in automation and machinery environments. It operates as part of a single-beam safety light curtain arrangement and is designed to detect interruptions in a focused optical path. The device supports integration into safety circuits where a dedicated receiver is required for monitoring protective beams.

• Single-beam detection enables straightforward fault diagnosis
• Safety performance rated to type4 for demanding applications
• Peak emission sensitivity at 660 nm for consistent optical response
• Maximum sensing range extends to 84 m for long-reach coverage
• Response time of 200 μs supports Rapid hazard reaction
• Screw Terminal connection simplifies secure wiring installation

• Suitable for perimeter guarding on automated conveyor systems
• Ideal for long-distance presence detection between machines
• Used with robotic cells requiring Compact receiver elements
• Can be used for access protection on production lines
• Suitable for retrofitting into existing single-beam safety setups

It employs screw terminals to create robust, field-serviceable wire terminations compatible with standard control wiring practices.

The receiver has an M30 cross-section with a 100mm body length, permitting mounting in confined equipment panels.

The receiver is configured for a single-beam arrangement and functions as the counterpart to a single emitter in a one-beam safety link.
