Safety Light Curtains (Machine Safety Light Barriers)
LNTECH provide two series of safety light curtains; the ST light curtain series with 10,20,40,80 mm beam spacing for limbs protection, and the SN light curtain series come with20,30,40,80mm spacing for limbs protection. These safety curtains are used for human protection and product/machine safety where risks cannot be eliminated by machine design and the process might require open and frequent access.
