Safety switches are indispensable in any application where safety is required for people and machinery. They are used for protecting movable physical guards, determining the position of dangerous movements, and the safe stop function. The portfolio is divided into electro-mechanical and non-contact safety switches, safety locking devices, and safety command devices. In conjunction with safe control solutions, SICK offers ideal complete solutions from a single source.

Safety switches with locking function lock protective devices securely and prevent access to areas which are protected by protective devices. Safety switches with locking function can be relied upon to prevent people from opening protective devices until dangerous states (machine overrun movements, for example) have passed or machine processes that cannot be interrupted have been completed.
