How Larco Industrial Safety Mats Work

For 60 years, Larco has focused its efforts on developing and producing the most reliable and durable presence-sensing safety mats available. Designed to meet stringent industrial requirements, Larco safety mats offer a durable solution to your machine safety needs, resisting severe environmental conditions with reliable system performance.

  • Larco presence-sensing safety mats work like a normal-open switch. When stepped on, the "switch" closes and sends a signal to the controller, which sends a stop signal to the guarded machine controls.
  • Larco control units provide intelligence to the system by monitoring the safety mat.
  • Larco safety mats can be secured using a variety of trim and mounting methods that are built for a number of environments, including areas with heavy forklift traffic.

Safety Mats - How tough are Larco Safety Mats? You can drive a forklift over them without damaging the inside components. How sensitive are they? Just 5-10 pounds of normal foot pressure activates the sensor. No wonder they’re the preferred safety mats for industries ranging from automotive and aircraft manufacturing, to factories that produce tires and wood products. Choose from a full spectrum of colors, shapes and sizes, with custom logo options.

Controllers - Larco Safety Mat Controllers allow multiple mats to operate together, making it easy to enable or disable industrial processes. Our mat controls maximize productivity by giving operators and service personnel access to operational and diagnostic status of safety mat deployment.

  • Maximize productivity with control
  • Quickly enable and disable industrial processes
  • Visual feedback on mat status

Applications - Larco Industrial Safety Mat Systems have been used for machine safeguarding to successfully reduce hazards in a number of industries in machine point-of-operation, area, and perimeter guarding applications, including:

  • Robotic Welding
  • Laser Welding/Cutting
  • Water Jet Machines
  • Pick and Place Robots
  • Plastics Molding Machines
  • Assembly Machines
  • Automated Material Handling
  • Packaging Machinery
  • Textile Machinery
  • Conveyors
  • Paper Converting Machinery
  • CNC Punches & Tube Benders

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
