Available with a wide range of functions and different designs, Turck's safety switches are suitable for dimensionally accurate monitoring of protective doors or positions. The product range includes everything from reliable mechanical safety switches (e.g. for use on door hinges) to safety sensors with contactless detection. Inductive sensors detect different metals without wear and represent a robust solution for users who wish to dispense with magnetic or mechanical counterparts. By contrast, contactless RFID safety switches offer specific tamper resistance with three selectable coding types, they allow cascading of up to 32 sensors and they are resistant to vibration.
