Installation
Common to A22, A22S/W, A22K, M22, and A22E
Panel Hole Dimensions
For 25-dia. holes, always use 25-dia. Rings. (Since the cutout dimen-
sions are large, IP65 cannot be guaranteed unless 25-dia. Rings are
used.)
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.
Note: Recommended panel thickness: 1 to 5 mm.
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.
Mounting to the Panel

2. The following panel hole dimensions apply when the Large-size
Pitches A and B between the centers of the mounting holes are as
follows:

3. When using a pushbutton with external dimensions exceed-
when the wires described under Applicable Wire Size on
page 165 are used. If a different wires are used, the wiring
dimensions may be different so determine an appropriate
pitch before setup.
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.)
ing 30 mm, use a pitch appropriate for the pushbutton.
