Safety light curtains is also named light barrier, light beam sensor. Tianjin G-TEK LDA series safety light curtain detection distance is 0.1m-12m. The self-diagnostic function can check fault circuit and give alarm. Interlocking reset, external test and EDM function enhance output monitoring capability. It can be used to protect all parts of body.
