Safety switches PSENmech, PSENmag, PSENcode, PSENhinge and PSENbolt

According to the standard EN 1088, hazardous machine movements must be stopped 
when a guard is opened and a restart must be prevented. It must not be possible to either defeat (VDE 060) or manipulate (EN 1088) these guards.

Certain applications also require the safety gate to be interlocked until the hazardous production process is complete. PSEN safety switches meet these requirements effectively and economically.

PSENmech mechanical safety switches are particularly suitable for applications in which the safety gate should not be opened unintentionally. Economical and reliable, they use increased extraction force on the actuator to ensure that a safety gate cannot be opened unintentionally. Mechanical safety switches with guard locking also ensure that the safety gate is interlocked until the hazardous production process is complete.

PSENmag non-contact, magnetic safety switches can be used when the risk analysis specifies a high category, where there is heavy soiling or where strict hygiene regulations need to be met. PSENmag switches are insensitive to spring-back or swinging from safety gates. This makes them particularly suitable for guards that are not aligned precisely.

The highest level of protection against manipulation can be achieved using PSENcode non-contact, coded safety switches. The enable from the safety device is only triggered if the actuating element is within the switch’s response range and the code number on the actuator matches that of the switch (key lock principle).

As one functional unit comprising hinge and safety switch, safe hinge switches PSENhinge monitor hinged safeguards such as gates or flaps. Direct actuation via the gate hinge saves installation space as well as providing protection against manipulation and defeat.
 
 

In areas where safety gates are opened and closed frequently or where safety gates are difficult to adjust, safety bolts PSENbolt provide a robust, complete solution comprising safety switch, handle and bolt. [... more]
