Note 1: The above table lists series names. Ask your OMRON representative for details on specific model numbers.

Note 2: Products that are certified for ANSI/ISA12.12.01 can be used in hazardous locations for Class I, Div. 2, Groups A, B, C, and D.

Description of Hazardous Locations:

[Class]

　　　Class I: Locations in which flammable gases or vapors may be present in the air in sufficient quantities to be explosive or ignitable.

　　　Class II: Locations in which combustible dust is present.

　　　Class III: Locations in which easily ignitable fibers or flyings are present

　　　but are not airborne in sufficient quantities to ignite.

[Division]

　　　Division 1: Locations in which explosive or ignitable material is normally present or is present at certain times.

　　　Division 2: Locations in which explosive or ignitable material is not normally present (but may accidentally exist).

[Group]

　　　Class I:

　　　 Group A: Acetylene

　　　 Group B: Combustible gas/vapor, example: hydrogen

　　　 Group C: Combustible gas/vapor, example: ethylene

　　　 Group D: Combustible gas/vapor, example: propane
