■ Category 3, PLd construction example

[Precautions when using as Category 3 PLd]
Sensor redundancy is required!
Observe the following when connecting to the safety controller.
・In the case the product is used in a standalone state, the safety system may not operate properly when a sensor malfunction occurs.

CAUTION
The product cannot be used for human body detection.

■ Application examples

[Required conditions]

1.	The source of hazards is located inside the machine and may cause hazards to nearby people.
2.	The equipment is classified as Category 3 PLd or lower.
3.	The source of hazards is isolated only by the automatic door.
