Manuals for Safety Light Curtains (Category 4 / Type 4)
Safety light curtains use an array of photoelectric beams to sense intrusion into a plane of detection, offering protection where a process may require open and frequent access. Type 4 / Category 4 curtains achieve high fault tolerance through redundancy/monitoring, have a tighter field-of-view and are therefore less susceptible to optical short circuits.
