Hello,
we are using different types of sensors in our maschine.
encoders, light barriers etc.
Now we want to sell the machine in the USA.
We are now looking for UL-Listed/recognized parts. But we want to use also non listed parts.
Does the NEC permit the use of non listed/recognized sensors (24V), that are supplied from a class 2 supply.
The NEC describes in 725,2 Definitions:
"Due to its power limitations, a Class 2 circuit
considers safety from a fire initiation standpoint and provides
acceptable protection from electric shock."
Can we generally say, that components in class 2 circuit are not investigated.
Thanks for your help.
