SICK L21 Series Light Beam Receiver Safety Sensor 1 Beam 16m Max Range 200μs Response Time L21E-21MA1A L21E-21MA1A / 6034875

The SICK L21 Series Light Beam Receiver model L21E-21MA1A is a high-performance safety sensor designed for industrial automation and safeguarding applications. Featuring 1 beam detection capability and a maximum scanning distance of 16 meters, this receiver ensures rapid and reliable presence detection in automated systems.

Constructed with a compact M18 cylindrical housing measuring 97.7 mm in length, it fits conveniently into confined mounting spaces and standard M18 fixtures. The sensor operates at a peak wavelength of 660 nm corresponding to a visible red beam, allowing it to precisely detect compatible light sources.

Equipped with a maximum response time of 200 microseconds, the L21E-21MA1A supports rapid interruption detection essential for safety stop functions. Its Safety Type 2 classification complies with basic protective functions required in industrial safety settings.

Wiring is achieved through M12 connector screw terminals which provide secure and maintainable electrical connections suitable for field installations. The device supports a minimum scanning distance of zero meters, enabling sensing directly at the receiver face when required by the application.

This receiver is ideally used for conveyor end-of-line presence detection, machine guarding in single-beam monitoring setups, access detection on automated gates and doors, and object passage counting in packaging lines. Its robust design and quick response time make it suitable for harsh industrial environments.

Safety Type 2 certified rapid response for critical safety applications. Long sensing range of 16 meters for monitoring distant objects or access points. Visible red light beam detection at 660 nm peak wavelength. Compact M18 cylindrical form factor for flexible installation.

Reliable screw-terminal wiring via M12 connector. Zero minimum detection distance for close-proximity sensing needs.

Originating from Germany, this SICK L21 Series Light Beam Receiver integrates seamlessly into automation and control gear systems to enhance safety and operational efficiency. It is categorized under light detection and ranging sensors in industrial and manufacturing environments.
