Example) IP65: Dust-tight, Water-jet-proof type
"Water-jet-proof type" means that no water intrudes inside an equipment
that could hinder from operating normally by means of applying water for
3 minutes in the prescribed manner. Take appropriate protection
measures, since a device is not usable in an environment where a
droplet of water is splashed constantly.
Mounting
Caution
1. When mounting workpieces or jigs to the piston rod end, hold
the flats of the piston rod end with a wrench so that the piston
rod does not rotate. The bolt should be tightened within the
specified torque range.
This may cause abnormal responses of the auto switch, play in the
internal guide or an increase in the sliding resistance.
2. When mounting the product and/or a workpiece, tighten the
mounting screws within the specified torque range.
Tightening the screws with a higher torque than recommended may
cause a malfunction, whilst the tightening with a lower torque can
cause the displacement of the mounting position or in extreme
conditions the actuator could become detached from its mounting
position.
