Specifications Certified Standards Certification body * Certification for CSA C22.2 No. 14 is authorized by the UL mark. Standards and EC Directives Conforms to the following EC Directives: • Machinery Directive • Low Voltage Directive • EN ISO 14119 • EN60204-1 • GS-ET-15 TUV (EN60947-5-1), CCC (GB/T 14048.5) Item Utilization category Note: Use a 10 A fuse type gI or gG that conforms to IEC60269 as a short-circuit protection device.

Note: 1. The above values are initial values. 2. The Switch contacts can be used with either standard loads or microloads. Once the contacts have been used to switch a load, however, they cannot be used to switch smaller loads. The contact surfaces will become rough once they have been used and contact reliability for smaller loads may be reduced. *1. The degree of protection shown above is based on the test method specified in EN60947-5-1. Be sure to confirm in advance the sealing performance under the actual operating environment and conditions. Although the switch box is protected from dust,...

Safety Precautions Be sure to read the precautions for All Safety Door Switches in the website at:http://www.ia.omron.com/. Precautions for Safe Use Supplementary comments on what to do or avoid doing, to use the product safely. • Do not use the Switch submersed in oil or water or in locations continuously subject to splashes of oil or water. Doing so may result in oil or water entering the Switch. (The IP67 degree of protection of the Switch specifies the amount of water penetration after the Switch is submerged in water for a certain period of time.) • Although the Switch body is protected...
