Inductive Proximity Sensor Wiring Diagrams. Negative lead is black on m12 quick disconnect cables and blue on axial cables. The sensor detects metal objects 4 meters from the tip.
P np switched p ositive. The sensor detects metal objects 4 meters from the tip. Switched refers to which side of the controlled load relay small indicator plc input is being switched electrically.
Either the load is connected to negative and the p ositive is switched p np or the load is connected to positive and the n.
Switched refers to which side of the controlled load relay small indicator plc input is being switched electrically. The pnp inductive proximity sensor we will use can be obtained for just over 2 on ebay. If only the power line is wired internal elements may be damaged. Proximity sensor working principle.
