Characteristics
Note: 1.
To meet UL listing requirements with the H7CX-A11
@
models, an OMRON P2CF-11-
@
or P3GA-11 Socket must be mounted on the
H7CX. Otherwise, H7CX-A11
@
models are considered to meet UL508 recognition requirements.
2.
A waterproof packing is necessary to ensure IP66 waterproofing between the H7CX and installation panel.
