Cascaded Safety Light Curtains (4 light curtains connected in series)

OTKS03 cascaded safety light curtain can connect up to four light curtains in series, with a maximum of 288 beams. It also supports serial configurations for increased protection height, L-shaped configurations for multi-faceted protection, and U-shaped configurations, simplifying installation and wiring while saving costs for users. If a risk assessment determines that a controller is not required and level signal control is necessary, the OTKS03 cascaded safety light curtain can be used, integrating the controller function into the sensor and directly outputting two safe PNP or NPN signals.
