Space-saving access protection with safety light curtain

Automated pallet changing systems, which are loaded and unloaded by workers, are attached to CNC machining centers. When pallets are being changed in the machine, no worker may be in the hazardous area. A deTec4 safety light curtain in a device column with deflector mirrors protects the access point. With a resolution of 30 mm and a typical sensing range of 30 m, the protective field can be individually adjusted with deflector mirrors. This makes it possible to optimize the minimum distance to the hazardous point and the space required for the protective device. Several LEDs on the sender and receiver indicate the status of the deTec4 at any given time. If a worker leaves the area, the safety signal must be activated. As the reset button is directly connected to the extension connection of the receiver, the amount of cabling is kept to a minimum.
