key exchange unit by Haake Technologies protects workers from dangerous machines

At singly occuring faults, the system immediately changes to the safe condition: it switches off. If for instance in a safety edge a not perfect gluing of the end caps has been made, or sealing becomes worse because the glue becomes brittle, any ingress of insulating matter such as dust and dirt will not lead to a loss of the safety function

SAFETY INTERLOCKS and key exchange unit

High safety.

key exchange unit: Such guard locking devices are for instance key-operated mechanical interlocks, also called trapped-key systems. They are based on the easy-to-understand premise that a key cannot in two places at the same time - it can for instance be inserted in a switch OR be used for opening a guard.
key exchange unit: Another safety-relevant feature is that a key can only become free in a safe condition, when there are no hazards - a switch is turned off, a guard interlock is closed and locked. The big advantage of the system is the fact that a certain sequence of steps can be predetermined when designing the system. It is not possible to deviate from this sequence - thus a high degree of integrity is achieved. So virtually any hazard can be eliminated.
