Does Festo offers cables with sockets which have UL certification?
All valves that have UL certification and a 24V coil voltage are approved by UL with the provision that Class 2 power supplies as per NEC must be used. UL assumes that devices and components in a Class 2 circuit do not represent any fire or electric shock hazard, since Class 2 power supplies are limited in terms of both current and voltage and can thus be regarded as safe. For this reason, no cables with explicit UL approval are required in Class 2 circuits. The integration of Class 2 circuits into a particular overall system concept is ultimately regulated by the UL standard for the final product, the so-called end use standard. This is different for each product category and no general statement can therefore be made on this.
