x For 25-dia. holes, always use 25-dia. Rings. (Since the cutout
dimensions are large, IP65 cannot be guaranteed unless 25-dia.
Rings are used.)
x If outer surface treatment such as coating is performed for the
panel, the panel dimensions after outer surface treatment must
meet the specified panel dimensions.
Matrix Installation
1. The following panel hole dimensions
apply when Switch Unit and the
Standard-size Legend Plate Frame and
Lock Ring are mounted, and lead wires
are connected directly to the Switch
Block.

70 mm min.
Note: 1. The above dimensions are the minimum dimensions for when the wires
described under Applicable Wire Size on page 23 are used. If a
different wires are used, the wiring dimensions may be different so
determine an appropriate pitch before setup.
2. With pushbuttons of external dimensions greater than 30 mm, set the
pitch according to the dimensions. (When using matrix installation for
the A22-M@, mount with a pitch of 40 mm instead of 30 mm in the
diagram above.)
Mounting the Operation Unit on the Panel
x Insert the Operation Unit (Pushbutton, etc.) from the front surface of the
panel, insert the Lock Ring and the mounting nut from the terminal side,
then tighten the nut. Before tightening, check that the rubber washer is
present between the Pushbutton Unit and the panel.
x When using a Legend Plate Frame, put one rubber washer each
between the Legend Plate Frame and the panel and between the
Operation Unit and the Legend Plate Frame. (One rubber washer
will be provided when one Legend Plate Frame is ordered.)
x Align the Lock Ring with the groove in the casing, then insert the
Lock Ring so that its edge is located on the panel side.
