Dimensions
- Unit: mm in
Cautions For Use
- Note that SF-AC cannot be connected to the NPN output (equivalent) type light curtain.
Wiring
Please install and connect ferrule (stick) terminal when the lead wire of the connected equipment is a twisted wire.
Please do not connect the twisted wire directly with the terminal.
Tighten the wiring to the wiring terminal block at tightening torque of 0.6 N m.
Others
The seal as shown in the drawing on the right is stuck to the engagement point of unit. When the seal is peeled off or broken, this equipment will not be certified as ‘Safety equipment’.
