A pair consists of identical twin units incorporating both photoelectric emitters and receivers in a single array across the full length of the housing to maximise use of space, with optimum performance that virtually eliminates blind zones and reduce the need for multiple spares. Visible LED indicators are installed along the full sensing height to indicate the functional state of each transmitter and assist in easy optical alignment. With specially developed brackets for rapid mounting, the light curtain has been designed for maximum machine availability. The SICK TWINOX4 hygienic safety light curtain offers high levels of protection with integrated Restart Interlock, External Device Monitoring (EDM) and beam coding along with OSSD’s for connection to a safety controller such as the SICK Flexi Soft system. Each SICK TWINOX4 housing is made from high-quality AISI 316L / V4A / 1.4404 hygienic stainless steel with a surface roughness (Ra) of 0.8μm, either IP65 or IP67, and a front screen of chemically hardened float glass. It is designed without overlaps, overhangs or seams and with radiused corners to eliminate residual contamination. Machine integration flexibility for both machinebuilders and end-users is assured with a choice of 300mm, 420mm and 600mm light curtain heights, over a width range of up to 4.5 metres. Operating temperatures range from -20°C to +55°C, hygienic and chemical resistant PUR cable is supplied with standard industrial M12 5-pin connections for the devices.
