Dimensions with Flush Mounting Adapter (Adapter and Waterproof Packing Ordered Separately)
H7CX-R[]-N

Panel Cutouts

Panel cutouts are as shown below (according to DIN43700).

Note: 1. The mounting panel thickness should be 1 to 5 mm.
           2. To allow easier operation, it is recommended that Adapters be mounted so that the gap between sides with
                hooks is at least 15 mm (i.e., with the panel cutouts separated by at least 60 mm).
           3. It is possible to horizontally mount Timers side by side. Attach the Flush Mounting Adapters so that the surfaces
                without hooks are on the sides of the Timers. If Counters/Tachometers are mounted side by side, however,
                water resistance will be lost.
