The new versions of the relays offer several advantages as compared to the non-transparent versions:
The new colour versions replace the previously used the transparent (clear) versions. This means that the previously used indexes and order codes with the suffix ...-01 remain unchanged. The colour of the transparent covers is automatically assigned depending on the coil type - AC colour orange, DC colour blue.. Ordering codes
Versions with transparent (clear) covers are available while stocks last.
Standard versions with non-transparent covers (solid, grey) remains unchanged! They are and will be produced without any changes.
