Safety Precautions
Refer to OMRON SAFETY COMPONENTS SERIES (Y106) for
common precautions.
Do not dismount the operation key from the door intentionally and
insert it to the switch with the door open. Machine may start
operating and injury or death may be caused.
Do not use metal connector or conduit with this switch. The broken
conduit hole may cause electrical shock hazard.
Precautions for Safe Use
