Proximity Sensor with All-stainless Housing E2EF Metal Head for long-distance Detection that Withstands Harsh Environments Where the Workpiece Can Rub against the Sensor Completely stainless-steel housing Long-distance detection equivalent to or greater than Proximity Sensors with Resin Heads *1 More than 20 times *2 the durability of Proximity Sensors with Resin Heads Spatter-resistant Models with fluororesin coating are available. Aluminum chip immunity Pre-wired Smartclick Connector Models are also available. *1. The actual sensing distance will vary with the size or material of the object. For details, refer to Engineering Data. *2. Test results for stainless-steel brush rotating at 130 rpm. Be sure to read Safety Precautions on page 4. Note: Models with a fluororesin coating also use vinyl chloride for the cable material and require separate protection. Ordering Information Sensors Refer to Dimensions on page 5.
