What is the difference between two-wire and three-wire sensors?
Two-wire sensors are wired in series with the load. Three-wire sensors have separate power and output wires and are common with PLC inputs.
For real industrial purchasing, the safest method is to compare the old part, the electrical input, the mechanical fit and the application before treating two models as interchangeable.
