Operation Characteristics (reference)
• The operation characteristics show the contact status when the
actuator enters into the center of the entry slot.
• The circuit No. 12-41 and 22-51 are interconnected. Use circuits
11-42 and 21-52 for safety circuits (In HS1L-R model, circuit 12-41 is
interconnected.)
