Proximity Sensor - 18 mm Diameter, Shielded, Normally Open - PNPThis 18 mm diameter shielded proximity sensor has a PNP output for compatibility with the native inputs on the SMI 2 ShopFloorConnect Machine Interface. This sensor is Normally Open, in other words, it actuates when metal enters the sensing field. Like other Wintriss inductive proximity sensors, this is a very useful general purpose sensor. It is immune to non metallic contaminants, oil resistant, and features an IP67 environmental rating. This sensor
