Tightening torque for auto switch mounting screw Auto switch model Tightening torque D-M9�ｭ(V) D-M9�ｭW(V) D-M9�ｭA(V) D-A9�ｭ(V) 0.05 to 0.15 0.10 to 0.20 (N・m) o12 o16 o20, o25 o32, o40 qInsert the nut into the auto switch mounting slot on the cylinder tube, and place it in the roughly estimated setting position. wWith the lower tapered part of the auto switch spacer facing the outside of the cylinder tube, line up the M2.5 through hole with the M2.5 female thread of the auto switch mounting nut. eGently screw the auto switch mounting nut fixing screw (M2.5) into the thread of the auto switch mounting nut through the mounting hole. rEngage the ridge on the auto switch mounting arm with the recess in the auto switch spacer. tTighten the auto switch mounting screw (M3) to fix the auto switch. The tightening torque of the M3 screw must be 0.35 to 0.45 N・m. yConfirm where the mounting position is, and tighten the auto switch fixing screw (M2.5) to fix the auto switch mounting nut. The tightening torque of the M2.5 screw must be 0.25 to 0.35 N・m. uThe detection position can be changed under the conditions in step t. qInsert the mounting bracket into the mating groove of the cylinder tube. wCheck the detecting position of the auto switch and fix the auto switch firmly with the hexagon socket head cap screw (M2.5 x 12L).. eIf the detecting position is changed, go back to step q. Note 1) Ensure that the auto switch is covered with the mating groove to protect the auto switch. Note 2) The tightening torque for the hexagon socket head cap screw (M2.5 x 12L) is 0.2 to 0.3 N・m. Note ) When shipping cylinders, auto switch mounting brackets and auto switches are shipped together. A 636
