Operation
Operation method, shapes of cam and dog, operating frequency, and
overtravel have a significant effect on the service life and precision of
a Limit Switch. For this reason, the dog angle must be 30 max., the
surface roughness of the dog must be 6.3S min. and hardness must
be Hv400 to 500.
To allow the plunger-type actuator to travel properly, adjust the dog
and cam to the proper setting positions. The proper position is where
the plunger groove fits the bushing top.
Bushing top
To allow the roller lever-type actuator to travel properly, adjust the
dog and cam so that the arrow head is positioned between the two
convex markers as shown below.

If failures, such as reset failures, in the plunger model are possible,
use a model that has a rubber cap.
Do not expose the Switch to water exceeding 70 C or use it in steam.
ALL DIMENSIONS SHOWN ARE IN MILLIMETERS.
