flexLock is very flexible when closing and locking your protective door and impervious to dust, contamination or water. Whether sliding or hinged doors, whether small or large closing radius – flexLock is easy to integrate into your machine and quick to clean.
Non-contact safety switches are the optimal solution if precise guidance of protective doors is difficult. Whether magnetic, inductive or via RFID, they are low-wear and low-maintenance when it comes to safe monitoring of doors or safe position monitoring.
The compact inductive safety switches from SICK play a key role in safe position monitoring, for example in AGV applications. The safety switches are not only small and versatile but also provide non-contact operation which keeps wear to a minimum.
The protection of machines can be varied: Doors and flaps are often indispensable for this and must be reliably monitored. This task can be performed by highly manipulation-proof magnetic safety switches or RFID safety switches with high tolerances to door offset.
A safe series connection is used to connect protective devices on machines. It reduces the number of safety capable inputs on the control and the amount of effort needed for wiring. For compact machines and combinable machine modules, SICK offers solutions from simple to complex.
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. Different safety tasks require different safety switches: Electro-mechanical and non-contact safety switches, safety locking devices, and safety command devices.
Optimal protection against manipulation thanks to RFID technology
For the safety of persons, the EN ISO 14119 standard defines manipulation protection measures that depend on the type and coding of the locking device. RFID technology is used to avoid critical situations that occur whenever an attempt is made to manipulate the protective devices installed in machines. This eliminates the need for costly design measures on machines.
Non-contact safety switches – intelligent solutions, low-wear and low-maintenance
Non-contact safety switches are well-suited if precise guidance of protective devices is difficult. They have very long service lives thanks to the low-wear and low-maintenance construction. They are also resistant to shock and vibrations and offer a high level of protection against manipulation. The portfolio is divided into three areas: Magnetic, RFID and inductive safety switches. Cuboid and cylindrical designs are available for each principle of operation.
Safety switches with locking devices 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.

Linking of protective devices via safe series connection
Different machine areas need different protective devices. They all have the same goal: To ensure that the machine stops safely in case of faults or danger. As complexity increases, so do the requirements for integrating safety sensors into the machine. The big challenge is safely connecting all safety sensors. The SICK solution: Safe series connection
