Proximity Sensor with All-stainless Housing E2FM 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. CSM_E2FM_DS_E_4_6 Be sure to read Safety Precautions on page 9. Note: Models with a fluororesin coating also use vinyl chloride for the cable material and require separate protection. Features For the most recent information on models that have been certified for safety standards, refer to your OMRON website. 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 severe conditions than ever. 0.8 mm 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. After 3 Minutes E2ESE2FM • Sodium chloride • Gasoline • Dilute sodium hydroxide • Dilute hydrochloric acid • Mineral oil • Barium hydroxide Any many others E2FME2EQ (Spatter-resistant) The E2ES with a top wall thickness of 0.2 mm was penetrated after 10,000 impacts. The E2FM was not penetrated after 250,000 impacts (depth: 0.26 mm). Note: Cannot be used for explosion-proof applications. The stainless-steel head means almost no wear when cleaned with a metal brush. More than 20 times the durability of the E2ES! 1
