For 25 mm-dia. holes, always use 25 mm-dia. Rings. (Since the
cutout dimensions are large, IP65 cannot be guaranteed unless
25-dia. Rings are used.)
If outer surface treatment such as paint is applied to the panel,
the panel dimensions after outer surface treatment must meet the
specified panel dimensions.

Locking should be applied toward the Engraving Plate.
Note: The above dimensions are the smallest-possible mounting
dimensions. However, these dimensions do not apply to
large Pushbutton Switches. For large Pushbutton
Switches, determine the distance between holes, taking
the Operational Unit and Legend Plate Frame into
account.

MOUNTING THE OPERATIONAL UNIT
ON THE PANEL
Insert the Operational Unit from the front surface of the panel,
insert the Lock Fitting and the mounting nut from the terminal
side, then tighten the nut. Before tightening, check that the rubber
washer is present between the Operational Unit and the panel.
When using a Legend Plate Frame, put one rubber washer each
between the Legend Plate Frame and the panel and between the
Operational Unit and the Legend Plate Frame. (One rubber
washer will be provided when one Legend Plate Frame is
ordered.)
Align the Lock Fitting with the groove in the casing, then insert
the Lock Fitting so that its edge is located on the panel side.
Tighten the mounting nut at a torque of 0.98 to 1.96 N m{10 to
20 kgf cm}.
When using a Lock Ring, replace with the supplied Lock Fitting,
insert the projecting part into the lock slot, and then tighten the
mounting nut.

When the panel cutout dimension is 25 mm dia., remove the

shown below. (Since the A22Z-R25 is not attached to the main
