Flush and nonflush mount models are available with standard or extended sensing distances, with complete overload protection. These IP67-rated sensors are made of nickel-plated brass or 304 stainless steel. PNP models are IO-Link-compatible and are available with either a normally open or normally closed output. NPN logic also is available with a normally open output. M12 quick-disconnect termination also is available on all sensor sizes; a 2-m pigtail cable is an option on 8- and 12-mm sensors.
