*The armature pull-in and release times are reference values under no load in a stationary state. They are generally longer depending on the size of the load and the operating state when engaged.

*The allowable rotation speeds of engagement NF and NS indicate, respectively, full-depth tooth/full position and full-depth tooth/single position.
