Proximity Sensor with All-stainless Housing E2FM CSM E2FM DS E 4 7 Highly Durable Proximity Sensor for Tough Environments Completely stainless-steel housing Aluminum chip immunity Embedding installation to metal (steel) fittings Chemical resistance certified by Ecolab Europe Lineup includes pre-wire models and DC 3-wire NPN output models with fluororesin coating. Be sure to read Safety Precautions on page 9. For the most recent information on models that have been certified for Note: Models with a fluororesin coating also use vinyl chloride for the cable material safety standards, refer to your OMRON website. and require separate protection. Features One-piece completely stainless-steel housing with a face thickness of 0.8 mm The face thickness is approximately 4 times that of previous models (E2ES) to enable sensing in even more 0.8 mm severe conditions than ever. Brush Test Continuous Impact Test Chemical and Detergent Proof The one-piece completely stainless- steel housing of the sensing section withstands the following chemicals better. Sodium chloride Gasoline After 3 Minutes Dilute sodium hydroxide Dilute hydrochloric acid Mineral oil Barium hydroxide E2ES E2FM Any many others The E2FM was The E2ES with a top wall thickness not penetrated Note: Cannot be used for explosion-proof after 250,000 of 0.2 mm was applications. penetrated after impacts (depth: E2FM E2EQ 0.26 mm). 10,000 impacts. (Spatter-resistant) More than 20 times the The stainless-steel head durability of the E2ES means almost no wear when cleaned with a metal brush. 1E2FM Built-in Chip Immunity Chip immunity performance has been provided to greatly reduce false signals caused by spatter accumulation and other causes, almost eliminating the needs for cleaning, e.g., with metal brushes. Flush Mounting Extension distance Not influenced by surrounding installation environment. E2ES E2FM Note: When mounted in steel.
