Proximity Sensor - 12 mm Diameter, Shielded, Normally Open - NPN Controls This split core current switchThis 12 mm diameter shielded inductive proximity sensor is one of the most useful general purpose die protection sensors. This sensor has a threaded housing, and should be secured into an M12 x 1 threaded hole with thread locker. If the sensor is to be removed from the die during maintenance, epoxy it into a removable bushing or insert. This sensor is Normally Open, in other words, it actuates when metal enters the sensing field. This inductive
