Light grids & light curtains

Light grids and light curtains are non-contact safety guards for securing danger areas on machines

and installations. They use multiple beams of light to form an invisible safety light fence in front of the danger zone. When an operator interrupts one of these light beams, it will cause the safety outputs to turn off.

Light grids and curtains are used when

  • a machine operator must interact with the machine in very short cycles, for example at loading points for automatic assembly machines
  • hazardous work areas must be secured in a continuously interconnected material flow without disturbing the material flow
  • The danger zone must be secured on machines without safety fence

When installed vertically, light grids and light curtains serve the purpose of access control for operational personnel. When installed horizontally, they secure areas or prevent people from stepping behind them.

The difference between grids and curtains

The basic distinction between light grids and light curtains is the number of light beams used to create a protective field.

Light grids produce a protective field consisting of two to four light beams. Due to the large distance between the individual light beams, light grids are particularly suitable for access control in large work areas and for applications with a large distance between the operator and the dangerous movement.

Light Curtains consist of many light beams that can detect different body parts depending on the resolution (14-50 mm). A distinction is made between finger, hand and body protection.
