SICK L21 Series Safety Single Beam Sensor, 97.7mm Length, 16m Maximum Scanning Distance - L21S-21MA1A / 6034874


This safety single beam sensor is a sender unit designed for industrial machine safeguarding and presence detection in automation environments. It emits a visible red beam for object detection and integrates with common safety systems to provide a monitored protective function. The device connects via an M12 Interface and meets recognised European and UK conformity marks for use in regulated settings.

Features and Benefits:


• Peak emission at 660 nm enables visible alignment and detection
• Single-beam design simplifies installation and alignment
• Maximum scanning range 16 m extends detection reach
• Response time 0.2 MS supports Rapid interrupt signalling
• Minimum sensing distance 0 m permits very close-proximity detection
• Safety rating 2 provides a defined level of functional safety

Applications


• Suitable for machine guarding on production lines
• Ideal for presence detection in conveyor systems
• Used for access control at guarded openings
• Can be used for light-beam monitoring in robotic cells

What electrical connection does it require?


It interfaces through an M12 connector for power and signal wiring to compatible controllers and safety relays.

How does the device perform where close detection is needed?


It can detect targets starting at 0 m, allowing reliable operation for very near-field sensing tasks.

How quickly will it register an interrupted beam?


The sender supports a maximum response time of 0.2 ms, enabling fast signalling for safety circuits.

What physical form factor should installers plan for?


The unit has a Compact length of 97.7mm to assist with space-constrained mounting.
