The next generation of advanced light curtains, new SE4D safety light curtains offer high functionality with integrated features that include no dead zone, a muting function, EDM and blanking functions, IP67 protection and more! Offering the highest level of safety with Category 4, PLe, and SIL3 ratings, new SE4D light curtains offer your customers an advanced light curtain solution.
Conventional light curtains have a "dead zone" where there are no beam axis at both ends, but with new SE4D Safety Light Curtains, detection can be performed along the entire area! Since it isn't necessary to install them outside of the detection area, the SE4D light curtain can fit into almost any system.
Equipped with a muting function that causes a line to stop only when a person passes through the light curtain, but does not stop the line when an object passes through, this muting sensor and muting lamp can be directly connected to the light curtain so no special controller is required.
Because the light curtain has a built-in EDM (external device monitoring), a safety circuit can be easily constructed without a safety relay module, making it easy to downsize a control panel and reduce costs.
Fixed blanking function prevents the control output from turning off when a specific beam is interrupted, while floating blanking function prevents the control output from turning off when the number of beams interrupted is less than the set number.
SE4D light curtains are Type 4, Category 4, PLe, SIL3 with an IP67 degree of protection. Because of its dust and watertight structure, SE4D can be used in harsh environments over a long period of time without deterioration caused by water splash.
