Maximizing flexibility was the main development goal for the new Euchner CTS guard locking device. The result is a compact safety switch that produces a high locking force, is suitable for universal use in diverse installation orientations and can be mounted in various ways thanks to its expanded IO-Link communication capabilities and well-thought-out design. The CTS switch’s key innovation is the new FlexFunction feature, which allows a single device to perform a wide variety of functions that would otherwise require several switch variants. FlexFunction paves the way for new approaches to planning and operation.
