Leuze Safety Light Curtains

Reliable and interference-immune sensor safety technology ensures high system availability and productivity. Wherever man and machine work "hand in hand", our safety light curtains can be used vertically as hand and finger protection, as access guarding as well as horizontally as area protection. With respect to integration capability, availability and cost effectiveness, they meet the highest requirements.

MLC 500 Series of Safety Light Curtains by Leuze includes the newest generation of extremely sturdy type 4 safety light curtains. Three function classes – Basic, Standard and Extended – enable the most efficient use of devices from simple standard applications to complex controlled safeguarding processes. The devices can be used universally, due to the flexible fastening concept and the option of form-locking installation. In addition, the series offers custom solutions for further areas of application. These include extra slim design, AIDA-compliant pin assignment, integrated AS-i interface, protection classes IP67/69K as well as especially impact-resistant, cascadable or EX-certified models. 

MLC 300 Series MLC safety light curtains are the latest generation of extremely slim and robust type 2 devices with slightly set back front screen and reinforced side walls. The devices are available in the Basic and Standard versions, thereby fulfilling various requirements. They can be used universally, due to metal end caps, a flexible fastening concept and the option of form-locking installation. There are also variants which have an AIDA-compliant pin assignment.

Smart Process Gating (SPG) process is based on type 4 safety light curtains of the Leuze electronic MLC 500 Series.  It is implemented in the MLC 530 SPG variant.  In the basic principle, the SPG process uses two control signals:

  • The first signal (CS Control Signal) is provided by the system control (PLC)
  • The second signal (PFI, Protective Field Interruption is generated by the safety light curtain itself when the protective field is interrupted.

Advantages of Smart Process Gating (SPG)

  • Extremely compact, space-saving system design, since there is no need to make space for muting sensors in front/behind the light curtain
  • Outstanding reliability and availability of the safety device and low installation and service costs at the same time (no set-up/alignment/realignment of muting sensors)
  • Reduced risk of tampering by operating personnel
  • Even interrupted parts and pallets with gaps between loading are reliably transported
