Safe Interlocking is the safety locking solution with standstill monitoring – designed for applications with high requirements when it comes to safeguarding processes and people. The safe standstill monitoring function only unlocks the locking device when the system has come to a standstill. Thanks to SOS (safe operating stop), the drive does not need to be disconnected from the power supply. Safe Interlocking saves valuable space and ensures maximum productivity: no unnecessary downtimes, while ensuring safe, cost-effective, and standard-compliant operation of the system. The “safe monitoring of machine speed” function can be used when carrying out maintenance. Proven safety components from SICK increase availability and avoid follow-up costs.
