Dog speed: 0.5 m/s min.
If the speed of the overtravel dog is comparatively high, make the
rear edge of the dog smooth at an angle of 15 to 30 or make it in
the shape of a quadratic curve. Then lever shaking will be reduced.
Note:
Plunger Switches
If the dog overrides the actuator, the front and rear of the dog may be
the same in shape, provided that the dog is not designed to be
separated from the actuator abruptly.

The above y values indicate the ratio ranges based on TT
(total travel). Therefore, the optimum pressing distance of the
dog is between 50% and 80% (or 50% and 70%).

Stroke Settings vs. Dog Movement Distance
• The following information on stroke settings is based on the
• The movement distance of the dog based on the optimum stroke is
movement distance of the dog instead of the actuator angle.
The following is the optimum stroke of the Limit Switch.
Optimum stroke: PT + {Rated OT x (0.7 to 1.0)}
In terms of angles, the optimum stroke is expressed as
expressed by the following formula.
Movement distance of dog
Design the shape of the dog so that it does not come in
contact with the other roller lever when the actuator is
inverted.
