Recommended Mounting Holes
•
When mounting the Photomicrosensor to a panel with a hole
opened by pressing, make sure that the hole has no burrs. The
mounting strength of the Photomicrosensor will decrease if the
hole has burrs.
•
When mounting the Photomicrosensor to a panel with a hole
opened by pressing, be sure to mount the Photomicrosensor on
the pressing side of the panel.
•
The mounting strength of the Photomicrosensor will increase if
the Photomicrosensor is mounted to a panel with a hole that is
only a little larger than the size of the Photomicrosensor, in which
case, however, it will be difficult to mount the Photomicrosensor
to the panel. The mounting strength of the Photomicrosensor will
decrease if the Photomicrosensor is mounted to a panel with a
hole that is comparatively larger than the size of the
Photomicrosensor, in which case, however, it will be easy to
mount the Photomicrosensor to the panel. When mounting the
Photomicrosensor to a panel, open an appropriate hole for the
Photomicrosensor according to the application.
•
After mounting the Photomicrosensor to any panel, make sure
that the Photomicrosensor does not wobble.
•
When mounting the Photomicrosensor to a molding with a hole,
make sure that the edges of the hole are sharp enough,
otherwise the Photomicrosensor may fall out.
