Frequently asked questions
Will 1FK7042-5AF71-1SG5 drop into a panel specified around 1FK7042-5AF71-1DB0?
They share the same 1FK7042 frame and family, but the suffix codes govern encoder, holding brake, shaft, and connector options — those option fields have to be matched against the existing panel before a drop-in decision is made.
