1.3.1 With keyway (Model code: K)
It is available as an option with a keyway for positioning on the output shaft of rotary axis.
1.3.2 Home Limit Switch (Model code: L)
In ordinary home-return operation, the “pressing method” is adopted in which the actuator is pressed
against the stopper and detects the Z-phase after reversing.
The “Home limit switch” is an option that does not adopt this pressing method but adopts a proximity
sensor to perform the home-return operation.
