Free choice of space for the safety: Mirror columns from SICK are used in applications where protection of hazardous points, e.g. machining centers, on several sides is required. The combination of multiple light beam safety devices with mirror columns used for beam deflection is the right solution here. Since multiple sides of a machine can be protected with a single pair of sensors devices, the overall wiring is reduced. The deflector mirrors can be easily adjusted in the rugged columns. Unhindered access for loading and changing tools and programs is a further advantage of using deflector mirrors over mechanical fencing and leads to increased productivity.
