■ 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]
2. The equipment is classified as Category 3 PLd or lower.
3. The source of hazards is isolated only by the automatic door.* The product can be used safely when all of the above conditions 1 through 3 are satisfied!* There are cases where you can use it under other conditions.
* Be sure to read the “Cautions For Use” when using for safety applications.
Alleviates interference without slits, allowing close-spaced installation
With about half the light diffusion of previous models, narrow-beam models can be placed twice as closely together-without the added cost of purchasing and installing slits.
Detects minute objects with a diameter of just 0.5 mm 0.020 in, without slits [EX-11S□]
With about half the light diffusion of previous models, narrow-beam models can detect minute objects with a diameter of just 0.5 mm 0.020 in, without slits.
These models provide a reasonably-priced solution for applications requiring detection of minute objects.
IP67 protective structure
The sensors features an IP67 protective structure to allow their use in process lines where water is used or splashed.
Rust-resistant stainless steel sensor mounting brackets and screws are available.
Note: If water splashes on the sensor during sensing operation, it may sense water as an object.
Long-range sensing at 1 m 3.281 ft with a narrow-beam [EX-19S□]
Narrow-beam models deliver long-range sensing at 1 m 3.281ft.
